When 1.5 was released, I setup a new Samba server.  About every week or
two, I upgraded to the latest 1.5-release.  Sometime in the last month or
so, Samba would stop serving files and I would get the message to increase
NMBCLUSTERS.  

Sometimes it is OK, sometimes it stops transferring packets.  I have just
started trying to get a good network trace when it fails.

I have been upgrading hardware in the last month also to see how much
throughput I could get from the file server.  I have upgraded from ISA to
PCI ethernet nics, a 10 Mbit hub to 100 Mbit switch.  So upgrading software
has not been the only change on my systems and network.  

But this seems odd.
