Hi guys,
I need a help with issue. Our customer is having 9200L as edge switches (varied models due to PoE demands), some stacked, mostly not.
We are running Ansible automation and push commands every night around midnight. And there is one stack which crashes with "Critical software exception"
It is stack of 2x C9200L-48PL-4X
Non stacked C9200L-48PL-4G is fine / stacked 2x C9200L-48P-4X is fine too
This was happening on 17.09.06a and continues to happen on 17.12.06
Crash logs are full of following messages:

It is always "SSH Process" so I do suspect some kind of memory leak.
Do you have idea how to stabilize this?
Customer wants to have CVE-2025-20352 fixed.
We need to have custom privilege commands for operators, but those are not saving due to bug (yes, thats why we push them in by Ansible on regular basis) CSCvs54882 https://quickview.cloudapps.cisco.com/quickview/bug/CSCvs54882
It is like minefield to navigate thru.
Thanks for help
