freezing samba

I'm running Samba 2.2.3a-14.1 for Debian, and every now and then when I
access a file from my WinXP machine, the program accessing the file in
Windows will freeze for almost a minute before opening the file. I think
both Windows and Samba are at fault here: Windows for hanging until the
program can read the file, and Samba for delaying this transaction (for
whatever reason), but I think I can fix the problem with Samba (don't know
about Windows).

The machine running Samba has 128MB RAM, and does not appear to be affected
by this behaviour in that I can still issue commands at the command prompt
via SSH.

Most of the time, I can open shared files very quickly. Sometimes, I
accidentally try to access files for which I haven't granted myself
permissions yet, though this should instantly return an error in the Windows
application, shouldn't it?

Any ideas where to start debugging this would be appreciated.

Is the application Word or Excel? I have the same problem, and after the
problem has occured, I find this a log-file under /var/log/samba/<pc>.log,
that says:

[2004/11/03 17:08:04, 0] smbd/oplock.cplock_break(758)
oplock_break: receive_smb error (Success)
oplock_break failed for file /SomePath/somefilename.doc (dev = 808, inode
= 1844384, file_id = 26583).
[2004/11/03 17:08:04, 0] smbd/oplock.cplock_break(843)
oplock_break: client failure in break - shutting down this smbd.

The name of the logfile (the <pc> part of the name, see above) is based on
the windows machine name.

I'm running Version 2.2.3a under RH 7.3

Yes! I get exactly the same error in my log file. I use Word and Excel, but
this also happens when I open files up with my text editor.

[2004/11/09 14:19:43, 0] smbd/oplock.cplock_break(758)
oplock_break: receive_smb error (Success)
oplock_break failed for file Summary-Paper.doc (dev = 304, inode = 33468,
file_id = 3).
[2004/11/09 14:19:43, 0] smbd/oplock.cplock_break(843)
oplock_break: client failure in break - shutting down this smbd.

Any idea what's causing this or how to fix it?


cheers,

What do you have in your samba config for 'opprortunistic file
locking' (probably misspelled). There are several ways to lock a busy
file in MS operating systems, and MS isn't always consistant.
