Hey guys,

I recently installed a fresh new PVE-Node that is running PBS as a virtual machine (no this PVE-Node is not the only one in the cluster).
I did this so many times on different environments but this never happened to me :(

The PBS VM shutsdown by itself on any random point during a backupjob from my "normal" Proxmox nodes.
I can't figure out or even know where to start. First I thought this only happens on VMs and not on LXCs, so I excluded the VMs, still the same. But it is happening on different points not always the same.

The only logentry I can find in the syslog is this:

PHP:

The log tells me that the VM is rebooting but it is not, it shuts down completly :(
Qemu-Guest-Agent is installed and running. PVE isn't telling anything so this can't be the actor that starts the shutdown via guest interaction.

The VM got the host as CPU with 3 cores and 6 GBs of RAM. Diskspace is 3.5 GB/18GB in use.

Can someone help me out for finding the issue?
