Hi,
When I have a network share mounted in a VM, and a lot of traffic is being written to the share, the whole VM freezes up. I found the following in journalctl on the VM:
Code:
Sep 13 15:17:56 kernel: CIFS VFS: \\192.168.1.247 sends on sock 0000000074f25f8c stuck for 15 seconds
Sep 13 15:17:56 kernel: CIFS VFS: \\192.168.1.247 Error -11 sending data on socket to server
Sep 13 15:17:56 kernel: CIFS VFS: Send error in read = -11
Sep 13 15:18:06 kernel: Status code returned 0xc0000128 STATUS_FILE_CLOSED
Sep 13 15:18:06 kernel: CIFS VFS: Send error in read = -9

The network share is on a FreeNAS box.

This first started happening after I upgraded to PVE 6.2-4 with kernel Linux 5.4.34-1-pve #1 SMP PVE 5.4.34-2. Previously I used PVE 5.3-2 and there was no problem.
Does anyone have any idea for how to solve this?
 
Solution was for me to stop being stupid :)
I upgraded to the newest kernel and the problem disappeared.
