Frozen GUI - Bad swap offset entry

[stanley75]

Hi there,

I'm quite new with proxmox pve. I'm using small personal server for home purposes with two running VMs. Occasionally pve freezes and GUI is unresponsive. Currently it looks like this:



CLI via SSH is accessible and running VMs too, but sometimes are VMs frozen. The following messages appear in the server log "pve kernel: _swap_info_get: Bad swap offset entry" (see below)

I have tried to recreate swap, but problem persist.

Can you please recommend me what I have to check, and how?

Thank you in advance, best regards Stanley
