As a result, the server no longer crashes when attempting to remove a connection from the active list. With this update, the server checks that the list pointers are valid before using them. If the pointers are invalid because the connection is not on the active list, Directory Server terminates unexpectedly.

However, the code that removes the connection from the active list expects that the connection has valid list pointers. Another remaining thread which detects that the connection is invalid also attempts to remove it from the active list. In this scenario, Directory Server moves the connection out of the active list and flags it as invalid. In certain situations, the number of active threads is less than the actual number of threads. When a thread flags a connection for closing, the server waits until there are no active threads left on the connection to remove the connection from the active list.
