[Samba] 3.0.21c winbind crash

[Thomas Limoncelli]

I'm using Samba 3.0.21c on SuSE 9.3 Pro (x86) with the binary RPMs from 
samba.org/suse.com (3.0.21c-2.1.2) on a Domain Member Server in ADS mode 
with winbind against W2K3 SP1 AD servers and idmap uids/gids stored in a 
central OpenLDAP directory.

After running successfully for some time, it now refuses to start after 
a reboot. The domain-specific winbindd instances are even crashing. :-(
Do the logs below ring a bell with anyone?

I'll try upgrading to 3.0.22 anytime soon, but I doubt that'll make a 
difference here.
