I have the following in my dmesg:

$ uname -a
Linux frank 2.6.17-1.2174_FC5 #1 SMP Tue Aug 8 15:30:44 EDT 2006
x86_64 x86_64 x86_64 GNU/Linux

It should be noted that lockd failed on this server at the same time.

Many entries like the flowing occurred on my NFS clients at the same time:
do_vfs_lock: VFS is out of sync with lock manager!
do_vfs_lock: VFS is out of sync with lock manager!
lockd: server 192.168.100.17 not responding, timed out
lockd: server 192.168.100.17 not responding, timed out

I'm reporting this, just as the error message asks. :)

Thanks!
