Server crashes every few weeks

[Mike_Richter]

Hi all.. i am new to proxmox and trying to figure this out.
Server started to crash every few weeks on random days/hours of the day

For months it was fine and then started to crash

I have few vms running - Ubuntu/Windows/TrueNas
13th Gen Intel(R) Core(TM) i5-13600K
64GB RAM


This is what i see in the System Logs

Nothing is the log to differentiate it from a power outages. Anything on the physical display when this happens (like a drive problem which would prevent logging)?
Maybe it's this: https://www.cpu-monkey.com/en/artic...4_gen_cpu_is_affected_by_instability_problems
