Can you attach to the process in this state and get gdb backtrace.
If the problem wasn't address with the report several months ago
it didn't give enough information to track the problem down. Maybe
you can do better ! :-). Log it as a bug at bugzilla please.

If it's a logic error in Samba we *will* fix it asap, sometimes
these can be hard to see. Also, sometimes it's an error in the
underlying system, not Samba.
