Doc Type: Bug Fix
Doc Text:
Cause: Under a very high load (hundreds of simultaneous connections and operations) the directory server could encounter a race condition in the connection handling code. Consequence: The directory server would crash. Fix: Move the code that updates the connection objects inside the connection mutex. Result: Directory server does not crash under high loads.

Description Rich Megginson 2013-04-27 01:57:35 UTC
This bug is created as a clone of upstream ticket:

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.
