[Samba] repeatedly crashing smbd when printing: broken pipe

[Daniel.Ammann at u-blox.com]

for months, we keep fighting issues with smbd 
(now at released 2.2.6), config is with spoolss, 
domain logon, and the client in question is an 
NT4 machine. server is a i386/linux 2.2.19

For a very long time, we thought it was related 
to oplocks, but now after having them disabled, 
it still is there.

Level 3 Log is as follows:

[2002/10/22 17:08:18, 3] smbd/ipc.c:reply_trans(480)
  trans <\PIPE\> data=1224 params=0 setup=2

[2002/10/22 17:08:18, 0] lib/util_sock.c:send_smb(704)
  Error writing 1264 bytes to client. -1. (Broken pipe)

And in the end, it will exit:

[2002/10/22 17:08:18, 3] smbd/server.c:exit_server(495)
  Server exit (send_trans_reply: send_smb failed.

Any ideas appreciated. And, yes, I will try to 
capture the event with Log Level 10.
