    USERS AFFECTED:
    WMQ users on IBM i trying to start FASTPATH channels and
    listeners

    iSeries
    
    ****************************************************************
    PROBLEM SUMMARY:
    WMQ was not allowing AMQRCMLA job to start a channel and/or
    listener in FASTPATH mode because it was being started as a
