Description Rich Megginson 2013-04-27 01:57:35 UTC

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/47349

Under heavy connection load, crashes are being randomly encountered.  This happens because we allocate and set c_private in the connection object after we put the connection on the active list.  Another thread can try to dereference c_private before it is allocated.
