Description Petr Baudis 2007-11-21 05:01:28 UTC 
gc() can overflow stack in case the cache has too many entries in it; since
stack size is only 1M per thread, this happenned for our customer at 124530
entries in cache on a heavily loaded nscd with many users and groups.

Comment 2 Ulrich Drepper 2007-11-23 06:39:23 UTC 
The change is too pessimistic when it comes to using the stack.  I've checked in
a modified patch.
