fan_control.service error

I had proxmox installed in a dell PowerEdge R710.
I Upgraded from v7 to v8 according to the instructions.
All went well and I am now on v8.1.4


From last night I get these readings on my Syslog

Jan 24 18:16:47 prox1 systemd[1]: fan-control.service: Scheduled restart job, restart counter is at 520.
Jan 24 18:16:47 prox1 systemd[1]: Stopped fan-control.service - Temperature-based fan speed controller.

Which is repeated every 5-10 seconds


The thing that got me searching for the logs is that I could not backup an LXC. It just stuck on "syncing" and when I clicked stop to stop the task it just hang.

When I restarted the system, it took nearly 30 minutes instead of the 2-3 minutes it takes generally.

Is there something I can do?

That fan_control service shouldn't be part of default PVE so you probably installed it yourself. Did you check if that service maybe isn't Debian 12 compatible?
Or if some additional python libraries are required?

Thnx. That was it
I might have installed it on version 7 for some reason I don't remember. Was unnecessary, removed it and all working fine again.
