[Samba] active connection gets lost in samba version 3.0 beta 3

Hi team,

A Samba "panic" occurs after repeatedly saving "word" files
on the server.

Following the panic the "active connection" disappears, but the
"active
shares" and "open files" stay.

Windows reports different errors such as "delayed write failed",
"Cannot complete the save due to a file permission error" etc.

Many of the Word files appear corrupted when reopening.

Our environment:
---------------------

 - Linux 9 Redhat
 - Samba 3.0 beta 3 (same problem on beta 2)
 - Server with 1 GB ram, lots of disk, 100 MB/s network
 - network switched

I have been searching Google, and been switching locks, time outs and
whatever for a day or so, but this didn't help.

The problem started suddenly, yesterday morning, and I can not think of any
network change causing the problem.
The beta 2 version worked fine for a number of weeks !

We are using Unicode filenames (including Hebrew, Arabic etc. characters),
but the problem occurs also with English
filenames, and from different computers (usually XP SP1)

The problem occurs also when the network is about empty.

Here is part of the log: (names changed)

[Samba] active connection gets lost in samba version 3.0 beta 3

Hi Jason

I switched off all the locking. This seems to be a nice bypass !

The "panic" still occurs every now and then , but the user gets:

"Word can not complete the save due to a file permission error".

If I press OK and "retry" it saves the file without problem.

On the Samba status page the "active connection" is gone, but I can go
on
working.

Thanks a milion.

David

I would try this first.  Get rid of any locking options in the shares and
make sure the global definitions have all locking options set to no.   Try
that and see what happens.  Good luck

Hi Jason,

With these parameters Word crashes as well, but the messages in the log are
very different.

Now I get "Transport endpoint is not connected"
"write_socket_data: write failure. Error = Connection reset by peer"
etc.

See the log.

Have you made certain that your Red Hat 9.0 is fully updated with the
latest errata? That is the first step. If then you still have a problem,
then you will need to compile Samba with the -g option and we need to
capture the same back-trace info. Armed with that information you should
post a bug report to https://buzilla.samba.org
