[Samba] problem saving word documents

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?

[Samba] problem saving word documents

Hello Johan.

I'm having a similar problem, except its on opening the word or excel doc on
the win2K machine.  Just a shot in the dark, but I think its got to do with
disk quotas, there isn't enough space, a word or excel doc takes up a heck
of a lot of space.  I thought this may be something new to look at, but the
errors seem to suggest oplock problems.

Hope you come right, tell the list if you do, I'll be looking for replies to
this subject.

Chow, Trevor.

Trevor,
I don't think that disk space is the problem. We're not using disk
quotas
and we're having 42 GB of free disk space.

Another thing I noticed is that when a user is unable to save a file , the 
log-files sometimes show that the client is, for some reason, opening and 
closing the file many, many times:

Is there some sort of explanation for this?

Am I right here to think that when oplocks are the cause, we shouldn't have 
these problems anymore when we disable oplocks on our server?
Cause we did that, but we still had the same problems.

[Samba] problem saving word documents

Just some random thoughts.

You seem to have oplocks on. They are on by default.  Have you thought
about strict sync and sync always. You have them set to no.  Have you
tried making them yes? Maybe look at strict locking, too.

These parameters are all share level parameters, too, and you have them
in your global section. I am not sure what that means.

The reason I didn't respond to your first post is that this is just a common
problem with oplocks, I thought anybody would have told you that.

[Samba] problem saving word documents

concerning strict sync - sync always - strict locking:
Well, I did take a look at those options, but because of what I read in the 
smb.conf man page, I thought I'd better leave them off (default). It looks 
like enabling them just slows things down?

When a share level parameter is set in the global section, doesn't that 
mean that that option then goes for every share?
I didn't put them there. I just left them at their default value (i.e. 
didn't put them in my smb.conf file)

Would you recommend disabling oplocks?

Cheers,

Your client reset the connection.  Possible network issues.

Your client 'went away'.  Possible network issues.

Fix this.  If samba every 'panics' then it is terminating itself with
extreme prejudice.  You *will* corrupt files - if your program doesn't
like having a half-rewritten file.

Samba is changing to a new group id, but when it double-checked, it had
not changed.  Do any of your users or groups have negitive GIDs?

No,
The full message we get is the following:

Sep 10 16:14:55 ls-aiv-03 smbd[15088]: [2002/09/10 16:14:55, 0] 
lib/util_sec.c:assert_gid(111)
Sep 10 16:14:55 ls-aiv-03 smbd[15088]:   Failed to set gid privileges to 
(-1,79999999) now set to (0,0) uid=(0,0)
Sep 10 16:14:55 ls-aiv-03 smbd[15088]: [2002/09/10 16:14:55, 0] 
lib/util.c:smb_panic(1092)
Sep 10 16:14:55 ls-aiv-03 smbd[15088]:   PANIC: failed to set gid

All our users have the same primary gid: 79999999
The uid of our users are in the range 10000 - 200000
Our machine accounts all have gid = 49999999
uid's of our machine accounts are in the range 900-1000

We left our guest account at the default 'nobody'
uid/gid of nobody is 99/99

But we don't make any explicit use of the guest-account in our smb.conf
file.
