Bug Description: A corner cases exists, where the slapd_daemon has begun its shutdown process but the accept_thread is still running and capable of handling new connections. When this scenario occurs, the connection subsystem has been partially deallocated and is in an unstable state. A segfault is generated when attempting to get a new connection from the connection table. Fix Description: The connection table is only deallocated when the number of active threads is 0. Modify the accept_thread to adjust the the active thread count during creation/destruction, meaning the connection table can only be freed when the accept_thread has completed Relates: 389ds#6119 Reviewed by:
