HA Periodic restarts every round hour

Configuration
1

I am running Home Assistant on top of Home Assistant OS inside Proxmox VM (based on the widely known tutorial) for 1.5 years.

Recently I noticed that Home Assistant is restarting every round hour (10:00 am, 11:00 am and etc.) and I couldn’t find any specific reason for it:

  • Home Assistant log does not report any log record before the restart
  • Proxmox has log like this:

Proxmox and HA are constantly updated and running the latest version. Updates did not fix this issue.

Any idea?
Tnx!

Answering myself:

There was a crontab running in Proxmox which failed to validate the health of HA VM and it restarted the VM.
