Severe system freeze with NFS on Proxmox 9 running kernel 6.14.8-2-pve when mounting NFS shares

Same issue here:
we had a perfectly working setup in PVE8 + OVS.
With PVE9 (fully updated) the load on the VM explode suddenly, the share are unaccessible and we have to reboot the VM).
The setup is as this:
- A bare metal NFS server (debian 13 fully updated)
- Several bare metal servers (rocky 9.7) NFS clients that encounter no problem.
- A VM mouting the same shares with NFS 4.2 (rocky 9.7 fully updated, we try several kernel with no luck. As of now we are on 6.17)

We are quite desesperate.
Please ask if more info needed.

same issue for me. tried everything in this post and others as well. going to completely kill this instance and start fresh on PVE8.
NFS shares unusable on PVE9 for me.
 
Do you backup this VM using the "Snapshot" mode (to a PBS server, for info) ? We deactivated the backup and the VM is up since 3 days which is a new record.
Maybe it has something to do with the freeze order send to the guest agent ?
 
Sorry for getting your hopes up :(
The load skyrocketted to 300 and the NFS shares are unavailable. This only occurs on this VM, not on bare-metal server.
I wish we could downgrade to PVE8 :(
 
I experienced this today. I upgraded this server to 9 a few days ago. NFS server is Truenas. NFS share set up as a disk and only used for proxmox run backups. Server became unresponsive to ping around 1:30 am. Didn't have time to manually check it but noticed it came back up around 7am. Later when i was on the machine trying to look at the logs I see that around 1:30 there are a lot of network unreachable errors regarding the NFS server. Then what looks like a reboot attempt but network doesn't come back up immediately. There is no gap in logs between 1:30 and 7am so the server was not entirely crashed. My analysis was incomplete because the server went away again while I was logged in.

I wanted to chime in because I don't think anybody noticed the network may come back up by itself after a long time. Might be a clue. I was hoping to switch to CIFS but people have been having issues with that too. That's a bummer.

EDIT: I have disabled the NFS share on the Truenas side, disabled the nfs storage on the proxmox server side and removed the mount. This particular server should not do any NFS calls right now. However I noticed that it just went down again. I am a little puzzled by this but I won't have access until it either comes up by itself or I take a walk to the server room next week. (As far as I can tell this was an unrelated kernel panic. Something to do with cpu power states. Prox 9 has been brutal on this old box)
