Apache ActiveMQ: What is TCP Port 64119 Used For?

I am running Apache ActiveMQ 5.5 on CentOS 5.5.

I have searched the ActiveMQ website, source code, configuration files, and I cannot fi开发者_开发技巧nd 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?

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).
