Hi everybody,

I have on my proxmox several lxcs running, a windows-vm and a home-assistant vm. For several months everything worked like a charme and I'm totally happy with my setup. But since a few weeks I encounter on my home-assistant vm a strange behaviour. Every two to three days in the middle of the night (when also an internal backup of home-assistant is running) the vm becomes unresponsive and the only way to get it back to work is to completely restart the vm. In the console I see the following output when this happens:

I already installed intel-microcode, but with no change in behaviour.

Can anybody point me in the right direction?

Thanks a lot in advance
Joerg
