Greetings,

Our problem will most likely drag out for a while so I thought I'd do a
summary that largely pertains to item to in my original post.

I received replies from:

Bill Hassell
Bob Marcan
Julius Szelagiewicz
Allan Marillier
Dave Johnson
Andy Cranston

The main feedback was to use Ethereal on the systems. It could do the
monitoring and figure out data from tcpdump and nfsstat also. We'll
give those a try and see what we find.

Thanks again to everyone and the original post is listed below.
