Hello,

I have a problem with my nodes on my Proxmox cluster. There are 3 nodes, that backup each week all the VMs to a NFS share.
Each week, during the backup, a node randomly freezes. I attached the onscreen error I see when it happens. When the server freezes, the VM are still alive and healthy, but no services are reachable (SSH, HTTPS, etc...)

I tried lowering the bandwith of the VM backup (50000 KBPS set in vzdump.conf), and I also tried setting a different schedule for each node. (thursday, friday and the last node is on saturday)

Thanks in advance for any help
