Could somebody HELP!? oplock_break problem, tdb corruption

[Olaf Frączyk]

Hi,
As I found on samba, samba-technical groups, I'm not the only one who has 
these problems.

Can somebody give some help?

Some info again:

I have following symptomps:

In sample log (logs for smbd per machine):

And similar.

After that smbstatus shows garbages:

Or simply stops in listing connections and tells, that database 
connections.tdb is corrupt.

Afterwards, from time to time, users cannot connect to samba, and it has 
to be restarted.
