No firewall on either end and server responds to ping.

However I just rebooted the nfs server. But when I checked before lockd 
was running with a ps -A
As Craig said he started notice this about the the time he upgraded to 
5.2, the same goes for me, started getting this problem about the time 
I've upgraded the clients and server.
