Proxmox host stops responding, LXC continues (infosec.pub)

I'm running Proxmox 9 on a server with currently a single LXC running. On no apparent time schedule, within a day but frequently within an hour, the host will stop responding to SSH, pings and the web UI stops updating. However, the LXC continues to run happily. The only way to bring the host back up is to power cycle the server.

Has anyone got any troubleshooting tips?

Hardware issues are often the case. I'll put my advice as a top comment.

Good point. All my VMs were on a zfs array.

It seemed like enough of the system was in ram that it could still run, but anything that needed the root file system was out of luck.
