Proxmox machine rebooting sporadically

[SPQRInc]

Hello,

I just mentioned that my proxmox-system is rebooting from time to time when performing backup-tasks (bacula, not the proxmox-backup-system).

The logs are showing the following:

Any ideas on that?

Hi,
sporadic reboots I know from hardware (power supply, RAM, CPU/heat?) or bios issues only . If there kernel/driver issues you got normaly an kernel dump.

Why wouldnt you just use the backup system included in proxmox?

Hi,
I guess it's can't be an problem due bacula - more the higher load/temp/power.

I backup a lot of VMs/hosts with bareos (bacula-fork) without real trouble.
