I've seen software hang doing a fcntl(F_SETLKW) on an NFS-mounted file when lockd
was not running or was firewalled off. Essentially the client is asking for a
lock on a file -- which it never gets -- and the app waits forever for lockd to
respond.

I would check that lockd is running on the client and server, with rpcinfo -p,
and that it is not firewalled off.
