o  children in wrong state  (Tru64 UNIX)

    Another Event Dispatcher module entity is still enabled. Retry
    the command after you have disabled all of these entities:
    event dispatcher outbound stream, event dispatcher relay, event
    dispatcher relay logging, event dispatcher sink, and event
    dispatcher sink inbound strea.

 o  entity class not supported (OpenVMS)

    The Event Dispatcher is not registered with EMAA.  The NET$EVD
    process is probably not started.  For instructions on how to
    restart the Event Dispatcher, refer to
    HELP NETWORK_MANAGEMENT EVENT_DISPATCHER.
