[Samba] winbindd 3.0.10 stops functioning

Fri Jan 7 18:18:36 GMT 2005

I've recently upgraded from a 3.0.4 (or 3.0.6, I don't remember) to 
Samba 3.0.10 on a FreeBSD 5.2.1 system and now I'm having problems with 
winbind.

It seems to run fine for a while, but then it hangs and starts taking a 
lot of CPU time (80-90% while idling), eventually it dumps core.  I 
commented out the 'client use spnego' line because that caused winbindd 
to hang immediately after startup.  My smb.conf is attached.

I've attached the where from gdb of the core file, I have two core dumps 
from different days with the same stack trace.

I've also attached the last bit of the log.winbindd before winbindd 
stops functioning.  It's nothing exciting except it just stops.  On a 
side note I suppose all of those "No rid for..." messages should be 
telling me something, but I'm not sure what.

I did have one log which had the little note about looking at the BUGS 
section on the HOWTO and something about an INTERNAL ERROR, but stupidly 
I didn't put it in a safe place and I've lost it.

Thanks for any help you can give,
Joe.
