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 :(
