Fix

Description of problem:

Each one of these requires several seconds longer to complete than expected.

Version-Release number of selected component (if applicable): 1.9.80

How reproducible: 50%

This is caused by the event threading sleeping with a lock held when it should be doing a pthread_cond_timedwait()

Comment 1 Lon Hohberger 2009-02-19 16:53:32 UTC
This bug could cause temporary leaks in file descriptors, and if lots of services are in place, it could in theory cause rgmanager to run out of file descriptors (which should never happen).

Comment 2 Lon Hohberger 2009-02-19 16:54:01 UTC
After rgmanager wakes up from the sleep(), it should correctly close these file descriptors of course.
