Doesn't look like nfslock is running on the client?

What does /etc/init.d/nfslock status say?

Maybe related to this bug:

https://bugzilla.redhat.com/show_bug.cgi?id=453094

Try restarting nfslock on both client and server when it occurs?
Or try setting up a cron to restart nfslock hourly on all systems
to see if that can workaround the issue until a fix comes out?
