Hi everyone,

I'm experiencing an issue with one of my VMs when performing a backup using Proxmox Backup Server.

The backup process starts without any problems, but after approximately 10 GB of data has been copied, the VM enters a "CPU Stuck" state. This causes the VM to become unresponsive, effectively killing the server.

It's important to note that this issue only occurs when I initiate a backup for this particular VM.

Additional context:

  • I have other nodes with multiple VMs that are successfully backed up daily using Proxmox Backup Server.
  • This issue appears to be isolated to this specific node and its VMs.
Has anyone encountered a similar issue or have any suggestions for resolving this? Any help or insights would be greatly appreciated.

Thank you!
