Can you get a full debug level 10 log backtrace please.

Also, adding:

panic action = "/bin/sleep 90000"

to the [global] section of your smb.conf will
cause the crashed processes to wait on sleep,
allowing you to attach to them with gdb and
get a full stack backtrace which will help
us find the problem (we should never crash :-).

You might want to log a bug at bugzilla.samba.org
so we can track this.

Thanks !

Jeremy.
