We have also discovered that Samba sessions are disconnecting even though
the user is not accessing the NFS mounted directory. This is resulting in
lots of "dormant" samba processes, and Outlook etc complaining that another
machine has the file locked.
When the NFS directory is removed, the "dormant" processes disappeared.
