I have other machines it has occurred to as well. The only usage pattern I have is that it happened mostly while running Mentor's Precision, but I am doubting that that is relevant.

This is the line from /proc/mounts on Minnow:

192.168.1.27:/mnt/storage0/users /home/users nfs rw,v3,rsize=32768,wsize=32768,hard,lock,proto=tcp,addr=192.168.1.27 0 0

192.168.1.27 is our machine dolphin, which is running OpenSuSE 10.2 x86_64 on Intel(R) Xeon(R) CPU E5310 @ 1.60GHz with 4G of RAM, and is an XFS file system running on a Dell PERC5/i
adam@dolphin:~$ df -h /mnt/storage0/
Filesystem Size Used Avail Use% Mounted on
/dev/sdb1 2.8T 2.0T 807G 72% /mnt/storage0
from /etc/fstab
/dev/disk/by-label/storage0 /mnt/storage0 xfs rw,usrquota,grpquota 0 0
It is not running with inode64, but probably should be. Hasn't become a problem yet. Otoh, I understand that NFS v3 doesn't support 64bit inode numbers.
FYI almost all of our NFS clients are x86_64 Linux(except 2)

I have CC:d Fred Revenu, who was the person who brought it to my attention this morning that it had happened again last night.
