  - Fix functional issues after nosdn deployment

    After deploying with nosdn, it looks like there is some out of state
    issue between the services.  First guess looks like something is going
    on with the services and timing of registering to each other through
    rabbit.  Simply restarting the services seems to sync them back up
    correctly.
