Yes - somehow winbindd has gotten a linked list
corrupted and it's spinning going over that list.
I've seen this reported (on 3.6.x, not in 4.0.x or
above) but no one has ever been able to get a
reproducible test case/backtrace that would allow
us to track this down.
If you can I would be eternally grateful :-).
