I've had proxmox running for a couple of years now without issue. However, over the last few weeks I've noticed that the server seems to be crashing at random times, although it does generally seem to be in the early hours of the morning.
I've attached an excerpt from the log file from around the time of the crash, but here is where the crash seems to happen:
The "error fetching datastores" is expected as I tend to leave the Proxmox Backup Server offline until I'm doing my monthly backups. From what I can see the crash is sudden and not logged. I'm wondering if anyone else can spot anything which might hint as to what the problem is? Failing that, is there anything else I can do to try to work out what is causing the server to crash and reboot?
