Thank you so much for the reply, Jaime.  I actually figured out what the problem
was the yesterday, and it did indeed have to do with the NFS server.  The lockd
module on the server had been configured to run on a particular port, but the
module had actually never been reloaded, so it was still running on a random
port that was being blocked by the server firewall.  It's something that I
should have caught earlier.

I had actually tried this, but without the D_COMMAND.   I had thought
D_FULLCOMMAND would cover everything, but it wasn't really providing anything
that helped me debug.  Maybe because the daemon was just frozen and not able to
write anything to the logs?

Anyway, thanks again for the response.  I really appreciate it.
