samba - May 2002 - Error---semaphore timeout period has expired

I get the above error on Windows NT 4.0 and Windows W2k computers connected to a
Linux RedHat 7.2 Samba server.  Is there a setting I need to change to eliminate
this?  It only happens when the Samba server is under stress with a lot of
connections.  When this error occurs the workstation will break contact to the
Samba server and corrupt the indexes on database files we use.  Could it also be
a network card driver not functioning properly?  Guessing here.

Yes, I had this same problem, if not similar, just a few days after 
getting my Samba server box installed and working as the new file server 
in our office.

The problem ended when I changed-out of the LAN hubs (old non-fast 10 
mbs) with new autosensing switches. Turns-out, the new file server was 
too fast for the existing LAN infrastructure.
