MSG_ID_SYNC is broadcast to each node when a MSG_ID_JOIN has been received from all nodes. After MSG_ID_SYNC is successfully broadcast, the join handler is unregistered. However, if another MSG_ID_JOIN is received before the join handler is unregistered then MSG_ID_SYNC is re-broadcast. This results in multiple attempts to unregister the join handler. Once all MSG_ID_JOIN messages are received, unregister the join handler to ignore any extra MSG_ID_JOIN messages. Also, make sure that while join handler is being unregistered, MSG_ID_JOIN messages are ignored.
