nfsd: non-standard errno: -38

Hi,
My server is on kernel 6.6.13-1-lts and using ZFS. When i try to mount a nfs folder on the client desktop machine, the NFSv4 server crashes (dmesg listed below). Any idea what could be the issue?

Any idea what could be the issue?

Either of https://wiki.archlinux.org/title/NFS#Custom_export_root or https://wiki.archlinux.org/title/NFS#St … the_server ?

Thanks. I have now set ZFS based shares. Will keep an eye if there is a crash again.
