Resolution:
Resume is done to a subscriber where restart is done to a publisher.  

When the first GMD or load balanced message is sent by a given publisher on a particular topic, all RTclients on that subject are suspended, processing of messages on the subject is halted.  The publishing RTserver requests information from all the other RTservers regarding the clients they have which are receiving that subject. After an RTserver responses to the request a resume message is sent to that RTserver to 'resume' message processing for the given subscribers.  Once all RTservers respond to the request  the RTserver the publisher is connected to 'restarts' the publishing client.
