hi...

my log has quite a few of this error in it.

I am struggling to understand what might be causing this error ? The pid it provides does not seem to be active, so struggling to think what is causing it.

Anyone have any ideas or suggestions ?

I do run an NFS server, and set it up according to best practices for NFS in this forum.

Google is suggesting I add some modprobes to nfsd... but not sure this is best practice at unraid.

any help is appreciated....

Please post the diagnostics

here are the diags... stongly suspect sriov/vm as the root cause... but hard to tell...

I have been trying for months... to get sriov to work for cachyos guest... but no joy.

I did notice starting/stopping a vm tends to to trigger the error....

These errors by themselves are typically harmless, and I'm not seeing anything else relevant logged. Are you encountering any issues with the NFS mounts?
