Apache ActiveMQ: What is TCP Port 64119 Used For?

Question

I am running Apache ActiveMQ 5.5 on CentOS 5.5.

I have searched the ActiveMQ website, source code, configuration files, and I cannot find any reference to this port. Yet, when I start the broker, this is one of three TCP ports listened to by the JVM.

Does anyone know what port 64119 is used for by Apache ActiveMQ?

Answer 1

I have tried with ActiveMQ 5.4.2 on Ubuntu. It listens on:

• 61616 - broker protocol
• 8161 - web admin
• 39271 - JMX remote port

Server is not listening on any other ports.

EDIT: I checked with 5.5.0 and also restarted the broker (both 5.4.2 and 5.5.0) several times. JMX port is always different, looks like it's being randomized. I bet your 64119 changes over time as well.

To make it clear, connect to ActiveMQ broker with jvisualvm , you should see an open connection from jvisualvm to ActiveMQ process on this port (I can see it with lsof ).
