I found https://activemq.apache.org/components/artemis/documentation/latest/connection-ttl.html
and specifically this: "The client will automatically send "ping" packets periodically to prevent the server from closing it down." I assume by "client" they mean a java client supplied by a library. Of course, I am left without a clue as to what to do when implementing my own client in C++ to speak to ActiveMq over STOMP and Websockets. The doc doesn't really go into detail about what this "ping" looks like, which network layer it is on, or what form the response should take. Both the STOMP and Websocket protocols already have a heartbeat built in. Perhaps there is a way for me to say "Don't use this at all!" from my clients? Is it a header of some kind I would send on the CONNECT frame?
