VM randomly dies

[alex3025]

I have a VM (4 cores, 24GB ram) running Ubuntu 20.04 with pretty much only Docker installed.
In the last period happened that it randomly die.

The first time I got this problem was 15 days ago but all was fixed rebooting it but since today it keeps dying some time after its reboot.

With "die" I mean that I cannot connect to it with SSH, VNC from Proxmox UI and uptime, ram and cpu usage are freezed.

Did you check that hosts syslog for OOM logs?

Not yet, I'll do that tomorrow.

The host has 64gb of ram and normally it never go over 40gb with all the VMs and LXC containers running.

Ok so, I checked the hosts syslog and there are no OOM errors.
