Over the last three months using Proxmox (I have four nodes on my cluster), I feel that some VM's crash randomly. There doesn't seem to be a pattern of which VM that crashes - sometimes it's my router (Opnsense), sometimes it's a fedora, sometimes it's an ubuntu machine.

What is it that I can do here? I have obviously to set up some time of watchdog, but am I expected to see this?

Sometimes they crash (I had a kernel panic with OPNSense), but most time it's just that the VM crashes, I try to restart it, can't because of the lock thing, delete the conf file, and then I can restart it again. That has also happened with my OPNSense and with other VM's.

I am using 8.2.2 and 8.2.7 versions, and it seems to happen across my nodes.
 
Hi,
do you see anything inside the host's system log around the time of the crashes? What kind of lock do you mean exactly? Do the crashes happen after some operation like backup/snapshot?
