Hi there,
I don't know if this really is a problem with Proxmox Backup Server or with Debian or with my hardware. I couldn't find the source of my problems.
I had this problem about 4 times and I think this will not fix itself. The problem happened often after updating/rebooting but I couldn't link that to my situation.
The first symptom are login problems via ssh. It takes a long time to connect and if I leave the system running I cannot connect anymore.
Kernel Info: Linux pbs 7.0.14-11-pve #1 SMP PREEMPT_DYNAMIC PMX 7.0.14-11 (2026-08-06T23:36Z) x86_64 GNU/Linux
Here the relevant log for that:
I found some other errors in the log that my be linked to the problem above.
This was a one (I haven't counted) time event: [see attached file kernel one time.txt]
This was many times in the logs: [see attached file kernel multiple times.txt]
I don't know if those log snippets point the right way. So if you have other ideas...
And the end I have some funny error messages..
