Samba 2.2.0 causes Windows ME systems to lock, 2.2.0-alpha3 works fine, mostly

[Stephen D. Williams]

I have been running Samba 2.2.0-alpha3 (and alpha2 before that) for
several months on SuSE 7.0 with a 2.4.2 kernel and 6+ Win98 and
WindowsME workstations (and one Windows 2000 Server running in VMWare on
the same server).

We have been having occasional PC lockups or more commonly errors
complaining about what appears to be lost connections to the server. 
Looking in the log file, it appears to be a problem with locking.  I've
tried 'Server Oplocks' on and off.  The applications are shared data
accounting apps that use file locking extensively.  Restarting Samba,
and often also the PC's, causes everything to work again.  Alpha2 used
to lock up all machines.  Alpha3 complained about not getting a response
from the client and killed just a single thread.  The machine didn't
recover, but other clients were ok.

These messages were pretty common:
[2001/04/15 18:54:25, 0] smbd/oplock.c:process_local_message(374)
  process_local_message: unsolicited oplock break reply from pid 26375,
port 356
[2001/04/15 18:49:14, 0] smbd/oplock.c:request_oplock_break(998)
  request_oplock_break: no response received to oplock break request to
pid 2633  for dev = 306, inode = 44442, tv_sec = 3ada4ef5, tv_usec =
4485

This usually killed at least the machine involved:
[2001/04/15 18:49:14, 0] smbd/oplock.c:oplock_break(763)
  oplock_break: end of file from client
  oplock_break failed for file wfx32/ctx.ini (dev = 306, inode = 28547).
[2001/04/15 18:49:14, 0] smbd/oplock.c:oplock_break(854)
  oplock_break: client failure in break - shutting down this smbd.
[2001/04/15 18:49:14, 1] smbd/service.c:close_cnum(657)
  rts3 (10.0.50.40) closed connection to service
data                           


Naturally I upgraded to production Samba 2.2.0.  Upon first connection
to the server from the WindowsME systems, they lockup and refuse to do
anything else.  Win98 systems seem fine.  Reverting to Samba
2.2.0-alpha3 caused all machines to work again.

Since I am managing this network from 6000 miles away, I'd prefer not to
have to reinstall the clients.  The main client is an HP 1500Mhz Pentium
4 which of course shipped with Windows ME.  The server is an 800Mhz
Pentium III.
