[Samba] Mac OS X Server 10.3: Monotonically increasing Samba processes?

[Keith Bettinger]

Through my Server Admin, a graph of Samba "connected users" shows that 
the number of smbd server processes grows and grows without end -- 
processes never time out/log out and die.  This was no problem under 
light usage, but when I moved a heavily used share to the server, the 
number of processes spun out of control.

What made it all worse was that many of the supposedly dormant 
processes still took up 0.5% of the CPU, which, when the process 
numbers grew into the hundreds, did a nice job of locking up the 
server.

Can anyone else report a similar experience?  Is there a fix?
