Does it have something to do with UDP ports?
You haven't provided enough information to answer this question.
1. Is there any UDP port used in jboss as 7 or wildfly???
2. Doesn't HornetQ use UDP Ports?
Depending on the configuration, HornetQ will use UDP ports. Are you using a broadcast or discovery group? Are your clients using discovery?
3. What are <socket-binding name="messaging" port="5445"/> and <socket-binding name="messaging-throughput" port="5455"/> used for???
Would you please describe it in detail or Is there an article describe those ports???
Look in the messaging subsystem to see where those socket-bindings are used. You'll see that they are used for acceptors and connectors. See the HornetQ User Guide for more information on what these are for.
Thank you very much.

~~~~It seems that I must spend more time on HornetQ's architecture, examples, and user guide.
I must know more about it if I want to use it in more complicated production environment.
