ISE Node disjoins from deployment after running Show Tech

Hello All,

 

We are running SNS-3495 appliance with Version 2.2.0.470. There is already a bug hitting our PSN node due to "HeapDumpOnOutOfMemoryError". Considering the Bug behavior, there must be a triggering point for the bug. We are suspecting while we are running show tech for that particular node as the time matches very close twice.

From the logs, the admin logged out and all the services initiated stop responding

My query,

1. Running a show tech command can trigger the memory leak issue in ISE Nodes?

Hi @Jithishkk1514 

 you can try the:

ise/admin# application configure ise
Selection configuration option
...
[22]Generate Heap Dump
...

and check the result ...

 During the show tech-support command you can try (in another SSH)

ise/admin# tech top

and check CPU, Memory, and other ...

 

Hope this helps !!!

I understood the command, My query is

 

Running a show tech command can trigger the memory leak issue.?

Hi @Jithishkk1514 

 AFAIK the answer is no.

 I had a problem with the show tech-support command described here: CSCvt44403, but not related with Memory Leak.

 

Hope this helps !!!
