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?

Physically log into it and check the "vitals" (logs and resource usage)

If I had to speculate I would say that your network card has faulty firmware.
