random unresponsive proxmox and VM unreachable and requires hard reset. ver-8.2.2

[rahul.kamble]

I have a single node proxmox and with single VM on it. The system just goes unresponsive. We have to hard reset the server to bring it back online. This is happening regularly now. During this issue i see lot of traffic from this node.

Can someone help me to understand why is this system behaving like this and going unresponsive? logs are attached.


When i check the logs I see these from Dmesg.
