Could you please help me collect all .txt files from /storages/cores/ from the 3 Aps (AP ERC-02-AP49, AP ERC-02-AP51 & AP ERC-B1-AP03) so I can share it with our team for further analysis.
Please let me know your availability so I can collect the required logs.
Please feel free to let me know if you have any further queries.
Findings from crash logs:
1. From the two AP crash logs, it looks like they have different crash signatures.
Decoding one of the crash signatures, we found it to be similar to bug CSCvz08781, for which the solution is to upgrade to 8.10.161.
2. Since we were not able to find a hit for the second crash, we will have a discussion internally to see if this is a new issue.
Recommended to upgrade the SDA WLC to 8.10.181 as well.

I had a check internally and found that Wism2 is EOL and end of support and hence 8.10.183 is not available.
The last version released for Wism2 was 8.5.171.
Please feel free to let me know if you have any further queries.
Can we get 8.10.183.0 for wism2.
Its urgent.
Findings from crash logs:
1. From the two AP crash logs, it looks like they have different crash signatures.
Decoding one of the crash signatures, we found it to be similar to bug CSCvz08781, for which the solution is to upgrade to 8.10.161.
2. Since we were not able to find a hit for the second crash, we will have a discussion internally to see if this is a new issue.
Recommended to upgrade the SDA WLC to 8.10.181 as well.

Problem Description:
Initial issue:
When we had more number of clients connected to the APs(around 70-80 clients), few of them stopped catering to clients and after a reboot clients connected fine.
The crash was generated after rebooting the Aps to restore the network.
You had a fabric setup with over 4000+ Aps.
jan 30th : pinged internal to DE to find out if bug is fixed for 8.10.183
Here is a brief summary of our call:
1.
There is a query from Biswajit.
Can we upgrade the WLC 8.10.181.4 to 8.10.183.0, since 8.10.181.0 is deferred.
I believe the answer is Yes but wanted to double confirm from Cisco TAC.
I just got a confirmation from the DE team that 8.10.183.0 will be supported with DNAC 2.2.2.9 .
Compatibility Matrix should be updated by this week.
Please feel free to let us know if you have any further queries.
You are right.
I have requested for compatibility between DNAC 2.2.2.9 and wlc 8.10.183.
I will keep you updated as soon as I hear from the DE team.
Please correct , we need compatibility conformation on DNAC 2.2.2.9 with 8.10.183.0 from Cisco.
I just had a call with TAC engineer.
TAC confirmed on 2802i CCLIB certificate issue under https://bst.cisco.com/bugsearch/bug/CSCvy37953 buggy behaviour.
This issue is fixed under 8.10.171.0 and expected to have fix on 8.10.183.0.
TAC will share the findings shortly with logs.
Yes, Testing was done on 26th JAN for POVWLC1 and 4.
Below is the snippet.
Conclusion :- No compatibility issues found between 2.2.2.9 and 8.10.183.0.
+Baby John
Hi Satyam, you have tested this OS 8.10.183 in POV environment with DNAC 2.2.2.9 , did you find any issues ? Pls share.
I apologize for the confusion.
Yes, are you right 8.10.183 is not in the list of supported release for DNAC 2.2.2.9.
Since, 8.10.181 has been deferred and is not available for download, please allow me a day time so I can check with DNAC DE team if they can include 8.10.183 in the compatibility matrix and also get a confirmation if they have done some testing so you can proceed with the upgrade.
Please feel free to let us know if you have any further queries.
I also just noticed the same.
Below screenshot shared is from 2.3.3.6 ( by TAC ) but I concur checking the same for 2.2.2.9 compatibility with 8.10.183.0.
I have reached out Cisco TM on the same and expected to get response in 30 mins from TAC.
Hi Satyam / Sharath
Do note that the current production DNAC is on ver 2.2.2.9.
however, 8.10.183 is not in the compatibility list with DNAC 2.2.2.9 officially.
Cisco team, please advise if we still can proceed with the WLC firmware upgrade.
[Icon Description automatically generated]
I have a discussion with the DE, and yes the fix for the bug Is integrated to release 8.10.183 as well.
AP crash issue
Initial issue:
When we had more number of clients connected to the APs(around 70-80 clients), few of them stopped catering to clients and after a reboot clients connected fine. The crash was generated after rebooting the Aps to restore the network.
You had a fabric setup with over 4000+ Aps.
jan 30th : pinged internal to DE to find out if bug is fixed for 8.10.183
Here is a brief summary of our call:
1. You had 4-5 Ap crashes which were 2802i AP modes and we collected the crash logs and tech support logs from the affected APs.
2. Since you wanted SDA team to look into the fabric part to figure out if the are any issues with the routing part, I involved my SDA team on call.
3. As per our SDA teams analysis, the fabric underlaying path is not a traditional design and my colleague will give you more details about his findings and next plan of action.
Can we say if the bug is fixed in earlier release i.e.
8.10.168.0 and 8.10.171.0 which both are deferred now, will be fixed in 8.10.183.0.
Urgently.
The code 8.10.183 is currently not listed in the integrated releases for this bug.
Thanks for your support !!
Can you also confirm that this fix is integrated in 8.10.183.0.

the fix is to upgrade to 8.10.171 for the crash info seen for 9120 AP
Thank you for your email.
In this case I would recommend upgrading to 8.10.183 version which is the recommended version.
Here is the compatibility matrix for your reference:
Since the defect CSCvx96224 is fixed on 8.10.181.x, it is by default committed on 8.10.183.
Here is the link to 8.10.183 version:
https://software.cisco.com/download/home/286284728/type/280926587/release/8.10.183.0
Let me know if you are unable to download it, so I can publish it for you.
Please feel free to let me know if you have any further queries.
I can see that 8.10.181.0 is marked deferred now due to ongoing different bug CSCwd80290 <https://bst.cisco.com/bugsearch/bug/CSCwd80290> .
It is not available to download.
https://software.cisco.com/download/home/286284738/type/280926587/release/8.10.181.0?releaseIndicator=DEFERRED
Could you confirm that what can be done next ?
Hey Sharath,
Thanks for your confirmation and I hope everything is fine at your place.
In this case we can proceed with adoption of 8.10.181.0 instead escalation image 8.10.181.4.

Requested SDWAN team to share the 8.10.181 compatible firmware for SDWAN
Hi Vaibhav / Sharath / Kishor / Ramya,
Greetings !
As per understand provided on below mail trail it seems that we cannot have a stable SDI environment due to compatibility issues due to https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvx96224 bug is fixed in 8.10.181.4 which is not a SDI compatible.
@Kishorbabu C (kishobab)<mailto:[email protected]> and @Ramya M (ramym)<mailto:[email protected]> Please discuss internally and share an approach to get a fixed image from DE BU.
Suggestions :-
* Either 8.10.151.0 - which is SDA compatible image can have the SMU patch for this bug.
* Or 8.10.181.4 - can be engineered for SDA.
I checked and even for latest DNAC release 2.3.x ( 2.3.3.5 and 2.3.4) , I do not see 8.10.181.4 as supported/recommended image for SDA.
Thank you for the update.
Glad to hear that the Aps are stable now after the upgrade.
Let me request my colleague from SDA to assist with the compatible version.
@Vibhav Shinde (vibshind)<mailto:[email protected]>,
Could you please assist us with the 8.10.181.4 compatible versions for SDN?.
Thanks for your response.
I hope you would be doing well now.
As an update I would like to inform you that we have upgraded our on production WLC (TLDC-WLC2) to 8.10.181.4.
So far we have not received any issues of AP resetting capwap tunnel or radio resets causing client disconnections.
But upgrading WLC to fix code and migrating impacted site AP's to fixed WLC code is workaround approach which cannot be taken forward.
We require 8.10.181.4 compatible versions for SDN ( Fabric ) WLC's ( 8540's AirOS ) for long term solution.
Findings from crash logs:
1. From the two AP crash logs, it looks like they have different crash signatures.
Decoding one of the crash signatures, we found it to be similar to bug CSCvz08781, for which the solution is to upgrade to 8.10.161.
2. Since we were not able to find a hit for the second crash, we will have a discussion internally to see if this is a new issue
For CAPWAP traffic from WLC to AP takes path from Edge which might be the reason for CAPWAP keepalives to get dropped
Fro traffic from WLC to AP, we checked packet capture on AP connected port and we see source as a FE.

The crash signature matches the bug mentioned below which has a fix in 10.8.171.
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvx96224
Hi Ameera, we discussed the bug fixed engineering image is 8.10.181.4 (right ?)
We also discussed there is no fixed image for SDA, and Sharath shall help in getting engineering image for SDA WLC( presently running on 8.10.151.0 with DNAC 2.2.2.9).
Regarding packets drops against below logs, Cisco found this is happening when there is a load, which is causing the AP to go down.
That is the BUG.
Confirmed by Oliver( in CC) that when load is not there, packet drop also not there.
BUG description: Cisco Aironet Access Point (AP) radio may trigger a device to reload under certain conditions of high device data utilization leading to packet drops
Nov 22 11:08:24 kernel: [*11/22/2022 11:08:24.4998] Max retransmission count exceeded, going back to DISCOVER mode.
* Why are we saying that there is network issue (This could be due to packet drop between WLC and AP and suggested collecting caps.) ?
Is Cisco not convinced about the bug ? Pls clarify.
NCS maintenance team, Pls follow up with Cisco to get the image.
Thanks for the time on the call.
As summary:
* The logs from one AP is showing a wired side issue that the AP is losing the keep-alive packet and reached the max retransmissions.
* This could be due to packet drop between WLC and AP and suggested collecting caps.
* From WLC side we can increase the AP count and intervals :

* Regarding the AP crash we can see we are hitting this bug https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvz08781 which is fixed on the latest on 8.10.
As we agreed @Sharath Chandrashekar (sharcha2)<mailto:[email protected]> will reach the escalation team to check the below thing related to the bug:
* What is the amount of data/clients that the AP can handle before it crash .
* We need a fixed version that is compatible with a fabric network and DNAC version 2.2.2.9.

Could you please help me collect all .txt files from /storages/cores/ from the 3 Aps (AP ERC-02-AP49, AP ERC-02-AP51 & AP ERC-B1-AP03) so I can share it with our team for further analysis.
Please let me know your availability so I can collect the required logs.
Please feel free to let me know if you have any further queries.
Findings from crash logs:
1. From the two AP crash logs, it looks like they have different crash signatures.
Decoding one of the crash signatures, we found it to be similar to bug CSCvz08781, for which the solution is to upgrade to 8.10.161.
2. Since we were not able to find a hit for the second crash, we will have a discussion internally to see if this is a new issue.
Recommended to upgrade the SDA WLC to 8.10.181 as well.

Customer will perform the upgrade from 6 PM SGT to next day 7 AM SGT. They plan to do reboots at 12 midnight of 24th feb and 25th feb.
I had a check internally and found that Wism2 is EOL and end of support and hence 8.10.183 is not available.
The last version released for Wism2 was 8.5.171.
Please feel free to let me know if you have any further queries.
Can we get 8.10.183.0 for wism2.
Its urgent.

Recommended to upgrade the SDA WLC to 8.10.181 as well.

the fix is to upgrade to 8.10.171
During the upgrade customer was facing FN - 72524.
There is a query from Biswajit.
Can we upgrade the WLC 8.10.181.4 to 8.10.183.0, since 8.10.181.0 is deferred.
I believe the answer is Yes but wanted to double confirm from Cisco TAC.
I just got a confirmation from the DE team that 8.10.183.0 will be supported with DNAC 2.2.2.9 .
Compatibility Matrix should be updated by this week.
Please feel free to let us know if you have any further queries.
You are right.
I have requested for compatibility between DNAC 2.2.2.9 and wlc 8.10.183.
I will keep you updated as soon as I hear from the DE team.
Please correct , we need compatibility conformation on DNAC 2.2.2.9 with 8.10.183.0 from Cisco.
Yes, Testing was done on 26th JAN for POVWLC1 and 4.
Below is the snippet.
Conclusion :- No compatibility issues found between 2.2.2.9 and 8.10.183.0.
+Baby John
Hi Satyam, you have tested this OS 8.10.183 in POV environment with DNAC 2.2.2.9 , did you find any issues ? Pls share.
I apologize for the confusion.
Yes, are you right 8.10.183 is not in the list of supported release for DNAC 2.2.2.9.
Since, 8.10.181 has been deferred and is not available for download, please allow me a day time so I can check with DNAC DE team if they can include 8.10.183 in the compatibility matrix and also get a confirmation if they have done some testing so you can proceed with the upgrade.
Please feel free to let us know if you have any further queries.
I also just noticed the same.
Below screenshot shared is from 2.3.3.6 ( by TAC ) but I concur checking the same for 2.2.2.9 compatibility with 8.10.183.0.
I have reached out Cisco TM on the same and expected to get response in 30 mins from TAC.
Hi Satyam / Sharath
Do note that the current production DNAC is on ver 2.2.2.9.
however, 8.10.183 is not in the compatibility list with DNAC 2.2.2.9 officially.
Cisco team, please advise if we still can proceed with the WLC firmware upgrade.
[Icon Description automatically generated]
Can we say if the bug is fixed in earlier release i.e.
8.10.168.0 and 8.10.171.0 which both are deferred now, will be fixed in 8.10.183.0.
Urgently.
Hope you are doing well!.
I just received a confirmation that you can upgrade the WLC to 8.10.181.
Our SDA team ran a sanity check with version 8.10.181.0 and everything works fine with DNAC.
I would request you to go ahead with upgrading to 8.10.181.0.
Please feel free to let me know if you have any further queries.
Hi Vaibhav / Sharath / Kishor / Ramya,
Greetings !
As per understand provided on below mail trail it seems that we cannot have a stable SDI environment due to compatibility issues due to https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvx96224 bug is fixed in 8.10.181.4 which is not a SDI compatible.
@Kishorbabu C (kishobab)<mailto:[email protected]> and @Ramya M (ramym)<mailto:[email protected]> Please discuss internally and share an approach to get a fixed image from DE BU.
Suggestions :-
* Either 8.10.151.0 - which is SDA compatible image can have the SMU patch for this bug.
* Or 8.10.181.4 - can be engineered for SDA.
I checked and even for latest DNAC release 2.3.x ( 2.3.3.5 and 2.3.4) , I do not see 8.10.181.4 as supported/recommended image for SDA.
Thank you for the update.
Glad to hear that the Aps are stable now after the upgrade.
Let me request my colleague from SDA to assist with the compatible version.
@Vibhav Shinde (vibshind)<mailto:[email protected]>,
Could you please assist us with the 8.10.181.4 compatible versions for SDN?.
Thanks for your response.
I hope you would be doing well now.
As an update I would like to inform you that we have upgraded our on production WLC (TLDC-WLC2) to 8.10.181.4.
So far we have not received any issues of AP resetting capwap tunnel or radio resets causing client disconnections.
But upgrading WLC to fix code and migrating impacted site AP's to fixed WLC code is workaround approach which cannot be taken forward.
We require 8.10.181.4 compatible versions for SDN ( Fabric ) WLC's ( 8540's AirOS ) for long term solution.
I apologize for the delay.
I was on a medical leave for the past couple of days.
I analysed the AP13 crash logs and found that the reason the crash is radio slot 1 reload due to:
radio reloaded: sensord cmd(0x03) failed slot 1
[cmd timeout] wifi1: 0x9184=unknown intCode:0x1184 last 0x801c=SetRadio
The crash signature matches the bug mentioned below which has a fix in 10.8.171.
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvx96224
Could you please let me know if you upgraded the test WLC to the escalation image 8.10.181.4 and still see issues with crash or clients unable to connect?.
Please feel free to let me know if you have any further queries and I will be glad to assist you.
Hi Ameera, we discussed the bug fixed engineering image is 8.10.181.4 (right ?)
We also discussed there is no fixed image for SDA, and Sharath shall help in getting engineering image for SDA WLC( presently running on 8.10.151.0 with DNAC 2.2.2.9).
Regarding packets drops against below logs, Cisco found this is happening when there is a load, which is causing the AP to go down.
That is the BUG.
Confirmed by Oliver( in CC) that when load is not there, packet drop also not there.
BUG description: Cisco Aironet Access Point (AP) radio may trigger a device to reload under certain conditions of high device data utilization leading to packet drops
Nov 22 11:08:24 kernel: [*11/22/2022 11:08:24.4998] Max retransmission count exceeded, going back to DISCOVER mode.
* Why are we saying that there is network issue (This could be due to packet drop between WLC and AP and suggested collecting caps.) ?
Is Cisco not convinced about the bug ? Pls clarify.
NCS maintenance team, Pls follow up with Cisco to get the image.
Thanks for the time on the call.
As summary:
* The logs from one AP is showing a wired side issue that the AP is losing the keep-alive packet and reached the max retransmissions.
* This could be due to packet drop between WLC and AP and suggested collecting caps.
* From WLC side we can increase the AP count and intervals :

* Regarding the AP crash we can see we are hitting this bug https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvz08781 which is fixed on the latest on 8.10.
As we agreed @Sharath Chandrashekar (sharcha2)<mailto:[email protected]> will reach the escalation team to check the below thing related to the bug:
* What is the amount of data/clients that the AP can handle before it crash .
* We need a fixed version that is compatible with a fabric network and DNAC version 2.2.2.9.

Good day!
I went through the support bundle you provided.
Please find my analysis below:
This device is showing evidence of encountering CSCwd45843<https://bst.cloudapps.cisco.com/bugsearch/bug/CSCwd45843>: Java minimum heap value is to low which can lead to excessive garbage collection
Symptoms seen:
Authentication step latency on multiple policy evaluation steps.
High average request latency during times of peak load.
Authentication request latency does not recover until after the system is reloaded.
Mitigation:
Apply the universal hotfix to all nodes in the deployment and when available apply the patch with the fix for the installed ISE version.
The details of which are mentioned in my previous email to you as well.
Please find the log snippet below:

Garbage collector usage in RHEL: As long as an object is being referenced, the JVM considers it alive. Once an object is no longer referenced and therefore is not reachable by the application code, the garbage collector removes it and reclaims the unused memory. The reason GC is using more CPU cycles is that its aggressively reclaiming a huge amount of Objects which are not referenced anymore.
From the Catalina.out file we could see also the VCS threads being blocked:

Because of the above observations we see that you are encountering the bug CSCwd45843<https://bst.cloudapps.cisco.com/bugsearch/bug/CSCwd45843>;. There is a hotfix available for this bug:
https://software.cisco.com/download/home/283801620/type/283802505/release/HP-CSCwd45843
This is a generic HP and can be applied on any version and is available in CCO site, you could install it on all the nodes and monitor.
But we would suggests to install patch 6 first and then install this HP.
This bug is addressed in ISE 3.0 p7 which is yet to be released, until then you can install patch 6 first and then the HP over it.
Good day!
Thanks for the files you attached so far and I was able to come to a root cause of the issue.
Please find my analysis below:
From the tech top output we see a high CPU is consumed by the jsvc process:

Garbage collector usage in RHEL: As long as an object is being referenced, the JVM considers it alive.
Once an object is no longer referenced and therefore is not reachable by the application code, the garbage collector removes it and reclaims the unused memory.
The reason GC is using more CPU cycles is that its aggressively reclaiming a huge amount of Objects which are not referenced anymore.
From the Catalina.out file we could see also the VCS threads being blocked:

Because of the above observations we see that you are encountering the bug CSCwd45843<https://bst.cloudapps.cisco.com/bugsearch/bug/CSCwd45843>.
There is a hotfix available for this bug:
https://software.cisco.com/download/home/283801620/type/283802505/release/HP-CSCwd45843
This is a generic HP and can be applied on any version and is available in CCO site, you could install it on all the nodes and monitor.
But we would suggests to install patch 6 first and then install this HP.
This bug is addressed in ISE 3.0 p7 which is yet to be released, until then you can install patch 6 first and then the HP over it.
Do let me know if you have any further queries or concerns.

Good day!
I went through the support bundle you provided.
Please find my analysis below:
This device is showing evidence of encountering CSCwd45843<https://bst.cloudapps.cisco.com/bugsearch/bug/CSCwd45843>: Java minimum heap value is to low which can lead to excessive garbage collection
Symptoms seen:
Authentication step latency on multiple policy evaluation steps.
High average request latency during times of peak load.
Authentication request latency does not recover until after the system is reloaded.
Mitigation:
Apply the universal hotfix to all nodes in the deployment and when available apply the patch with the fix for the installed ISE version.
The details of which are mentioned in my previous email to you as well.

Garbage collector usage in RHEL: As long as an object is being referenced, the JVM considers it alive. Once an object is no longer referenced and therefore is not reachable by the application code, the garbage collector removes it and reclaims the unused memory. The reason GC is using more CPU cycles is that its aggressively reclaiming a huge amount of Objects which are not referenced anymore.
From the Catalina.out file we could see also the VCS threads being blocked:

Because of the above observations we see that you are encountering the bug CSCwd45843<https://bst.cloudapps.cisco.com/bugsearch/bug/CSCwd45843>;. There is a hotfix available for this bug:
https://software.cisco.com/download/home/283801620/type/283802505/release/HP-CSCwd45843
This is a generic HP and can be applied on any version and is available in CCO site, you could install it on all the nodes and monitor.
But we would suggests to install patch 6 first and then install this HP.
This bug is addressed in ISE 3.0 p7 which is yet to be released, until then you can install patch 6 first and then the HP over it.
Good day!
Thanks for the files you attached so far and I was able to come to a root cause of the issue.
Please find my analysis below:

Garbage collector usage in RHEL: As long as an object is being referenced, the JVM considers it alive.
Once an object is no longer referenced and therefore is not reachable by the application code, the garbage collector removes it and reclaims the unused memory.
The reason GC is using more CPU cycles is that its aggressively reclaiming a huge amount of Objects which are not referenced anymore.
From the Catalina.out file we could see also the VCS threads being blocked:
