samba - Sep 2003 - Winbind RC4 crash

Hi there,

We have just upgraded from Samba 3.0.0rc2 to 3.0.0rc4 on RH9 (stopped
smb/winbind, rebuilt from SRPM with ACLs enabled, rpm -Fvh to upgrade,
then started smb/winbind). Shortly afterwards, winbind crashed. Here is
an excerpt of the logs:

I have a snapshot of all of the Samba logs from the time of the crash
(at level 5) so let me know if further logs are needed.

Cheers,

Paul,

Any chance of getting a full backtrace?  Or maybe even testing the
latest SAMBA_3_0_RELEASE cvs branch?

Thanks.

	 https://bugzilla.samba.org/show_bug.cgi?id=437

although the cause if it may be different.

bye,
guenther

Looks very much like it. I have applied the backtrace script, hopefully
I can catch it next time it dies.  So far this week since the original
crash it has stopped working several times (wbinfo -g/-u fails) but
winbindd has continued running.

Cheers,
Paul
