I restarted the service postfix. Now there are no failed services.
Then I took a look into the system journal around 0330 in the morning, just after boot what the machine is doing and found other potentially related problems:
Jan 21 03:38:45 backup-vm auditd[713]: Error receiving audit netlink packet (No buffer space available)
…
Jan 21 03:38:00 backup-vm systemd[1]: Failed to start The Salt Minion.
Looking at https://monitor.qa.suse.de/d/GDbackup-vm/dashboard-for-backup-vm?orgId=1&from=1705800005138&to=1705814908962 I see that there are no problems with memory but potentially CPU
Using the virt-manager GUI connected to qamaster I now changed the CPU config to use CPU host configuration and bump the vCPU allocation from 1 to 2. I shut down the machine and restarted it and ensured it's properly up and running again. I assume this should resolve the problem. Alert gone. No error messages mentioned in system journal from salt or postfix or anything other obvious.
