I've encounter a problem where our WebSocket connections to ActiveMQ 5.13.3 are terminated abruptly. I thought, I might use WireShark to inspect the TCP layer for clues why the connection may be corrupted, but I'm not sure the ActiveMQ uses TCP protocol as its transport layer protocol for sending the messages.
All the kinds of clients and protocols which ActiveMQ supports use TCP as their transport layer. WebSockets specifically use TCP.
