recent 3 or so weeks, the system occasionally "freezes" happens every 2,3 or 4 days, cpu is pegged to 100% and I'm unable to open terminal to check "top" for what is causing the issue!! How do i proceed in finding the issue? last crash was approximately at 22:00 yesterday (19.feb)

Can you confirm that? Syslog in the diags goes from the 17th to today, I assume you were unable to get the diags after the crash? Or did it start responding again?

I can confirm that, was watching a movie which stopped playing. Every time it becomes responsive again, without any reboot.

I also have log from 8. feb, happened around 21:25, downloaded diagnostics afterward (no reboot).

I don't see anything logged that suggests an Unraid problem, are you sure the problem isn't with with your network/client device?

Thanks, me neither. But yes I'm sure, its not only an issue with SMB shares/network, the web-ui itself is horribly slow, I can see all cores are at 100%, unfortunately I'm not able to open terminal (web-ui) and check "top". But I will attempt ssh login and check next time. Unless i find something to log the cpu usage per app/docker/VM..

I have home-assistant and win-11 VMs, but they are not allocated all cores, and should not be able to cause all cores to show 100% utilization..

Hopefully i can catch it in SSH next time it appears.
