Check the accounting logs - use our tool if you want at
http://www.servergraph.com/techtip3.htm.

I bet you see a huge amount of idle wait. What may be happening is that the
directory stucture on the client is very deep, and the client is taking a
very long time to walk the tree - 4 million objects inspected! - and
IDLETIMEOUT is set too short (default 60 sec I think - most people set this
longer - on the TSM server as I recall) so that's why the node drops out a
couple of times a night.
