Any Oopses? (use 'dmesg')

Could you also check dmesg for any entries of the form

'lockd: new process, skipping host shutdown'
or
'lockd_up: makesock failed, error='

That could be a kernel process. The RPC client has no reason to set up a
full file descriptor for the socket.

Could you please finally double-check that the entries in /proc/mounts
for your NFS mounts do contain the 'lock' mount option.

Finally, please do

echo 1 > /proc/sys/sunrpc/rpc_lockd
then unmount one of your NFS partitions, and then mount it again.


Cheers,
