[Samba] problem saving word documents

[Johan Coenen]

Hi,

Thought I posted this already two weeks ago. Haven't seen any reactions 
yet, so I post it again

We got the following problem here:
Every now and then, users are unable to save Word or Excel documents on our 
Samba server. We already tried a couple of things: disabling oplocks, 
increasing oplock break wait time, putting the documents on a new share, 
... but to no success so far.

The problem seems difficult to reproduce, but we do have one log level 10 
file and a tcpdump.

the only errors we get in the logs are one or more of the following:

- read_data: read failure 4. Error = Connection reset by peer
( lib/util_sock.c:read_data(434) )

- Error: oplock break from client and no oplock granted on this file
( smbd/oplock.c:oplock_break(761) )

- oplock_break: client failure in oplock break in file ...
( smbd/oplock.c:oplock_break(833) )

- oplock_break: receive_smb timed out after 30 seconds.
( smbd/reply.c:reply_lockingX(4480) )

- Panic: failed to set gid
( lib/util_sec.c:assertgid(111)
   lib/util.c:smb_panic(1092) )

We're running Samba versions 2.2.4 and 2.2.5 and we're having these 
problems with both versions.
On our clients we have Win98, WinNT and Win2000, mostly Office 97 , a few 
office 2000.
Problem occurs with every Win/Office version.

Any ideas/suggestions?
