Proxmox suddenly stops responding, services still run for 30-60min

[gigagames]

Hey guys,
i have some weird problems with my Proxmox System.

At a Random time it suddenly stops working correctly
- The Webpage of the proxmox server is still reachable
- On the Summary page no addional data is shown in the Graphs

I force rebootet the System at arround 17:10, so between ~16:50-17:10 the server was still running, and all services still responding

- The Server and all contains get shown with a '?'
- An SSH connection to the Server isn't possible
- Opening the Console is not possible
- but all services run just fine and are accessible.

Restarting is only possible, if the power button is pressed / the power is cut

If i leave the server running 30-60minutes later, all services aren't reachable anymore

In the latest logs i have the following, can this be the reason? How to fix?

Hi,
sounds like it might be a kernel issue. You could try the newer kernel from the test repository: https://pve.proxmox.com/wiki/Package_Repositories#sysadmin_test_repo
You can temporarily enable the repository, run apt update, run apt install proxmox-kernel-6.8 and disable the repository again (e.g. via the Repositories section in the UI), then run apt update again.

Alternatively, you can try booting into an older kernel.

I'd also make sure to have the latest CPU microcode installed: https://pve.proxmox.com/pve-docs/chapter-sysadmin.html#sysadmin_firmware_cpu
