In the following I show that about 40 minutes into an across-the
network-backup, the remote mount-point becomes inaccessible.
Both machines are running Linux 2.2.1 The server is running a
Red Hat 5.2 release. The client is running software accumulated
over several years (not a vendor release).

Neither the client, nor the server appear to run out of memory.
There are no entries in the logs of either machines to show the
problem.

This is 100% repeatable.
