I seem to have the exact same problem in my environment - I have three
domains, and it seems that at some point multiple winbindd instances go into
infinite loop in the same location in winbindd_dual, because of duplication
in the winbindd_child list:

(gdb) print winbindd_children
$1 = (struct winbindd_child *) 0x74bb58
(gdb) print winbindd_children->next
$2 = (struct winbindd_child *) 0x74bb58

Is there any progress of investigating it? I will keep my logs/core dumps
and provide them if needed.

Thanks!
