How to use the gateway-mq?

Issue

I'm in the process of setting up a new A-MQ dev platform within a Fabric environment. I currently have one master/slave pair that is working correctly. I have recently implemented the use of gateway-mq. I'm noticing that when I stop either the master or slave and leave it down the gateway no longer works, seems like both master & slave must be running. I'm wondering if I have a configuration issue or if there is something else going on. I'm using the gateway-mq profile within my broker group profile along with gateway properties file io.fabric8.gateway.detecting.properties that I have customized.
