[Samba] The smbd ran away with the spoon...

It seems that my smbd process got fuxed somehow.  It appears to have
take up all the file handles, and there were over 130 smbd processes
running on the system.  I'm not entirely sure what happened.  My first
thought is that something bad happened between the server and the
Windows client that's running Kaza (with a couple hundred mid-download
files) and it just spiraled out of control, but I figured it wouldn't
hurt to post some log info and my smb.conf file here and see if anyone
has any other ideas.  For reference, I'm running Samba 2.2.6pre2 on
Mandrake 9.0.

The following was repeated many, many times in the samba log file for
the Windows client in question:
[2002/11/22 17:08:06, 0] lib/util_sock.c:write_socket_data(499)
  write_socket_data: write failure. Error = Broken pipe

[2002/11/22 17:08:06, 0] lib/util_sock.c:send_smb(704)
  Error writing 53 bytes to client. -1. (Broken pipe)


The following is the smbd log file since the last startup:

[Samba] The smbd ran away with the spoon...

Done, thanks.

Just out of curiosity, with Samba acting as my Windows domain
controller, about how many smbd processes should I expect to see on a
network with about half a dozen active windows clients?  By "active" I
mean that one of them is constantly accessing Samba shares for purposes
of tape backup, another is constantly accessing a Samba share for
writing to its many mid-download Kazaa files, and the rest are sparingly
accessing the Samba shares for sharing files/running shared
programs/etc.
