Bug 727558

Description of problem:

$> bin/rhq-agent.sh --cleanconfig --purgedata -p brand-new-and-unused
RHQ 4.1.0-SNAPSHOT [b3eb971] (Mon Aug 01 21:40:33 CEST 2011)
Answer the following questions to setup this RHQ Agent instance.
- After each prompt, a default value will appear in square brackets.
  If you press the ENTER key without providing any value,
  the new preference value will be set to that default value.
- If you wish to rely on the system internal default value and
  not define any preference value, enter '!*'.
- If you wish to stop before finishing all the questions but still
  retain those preferences you already set, enter '!+'.
- If you wish to cancel before finishing all the questions and revert
  all preferences back to their original values, enter '!-'.
- If you need help for a particular preference, enter '!?'.

Agent Name [localhost.localdomain] : 
Agent Hostname or IP Address [!*] : 
Agent Port [16163] : 16164
RHQ Server Hostname or IP Address [127.0.0.1] : 
RHQ Server Port [7080] : 7085
The setup has been completed for the preferences at node [/rhq-agent/brand-new-and-unused].
!!! This agent is registering under the loopback address [socket://127.0.0.1:16164/?rhq.communications.connector.rhqtype=agent&numAcceptThreads=1&maxPoolSize=303&clientMaxPoolSize=304&socketTimeout=60000&enableTcpNoDelay=true&backlog=200] - this should only be done for testing or demo purposes - this agent will only be able to interact with a server running on the same host as this agent

!!! There are [1] servers that are potentially unreachable by this agent.
Please double check all public endpoints of your servers and ensure
they are all reachable by this agent. The failed server endpoints are:
[localhost.localdomain:7080/7443]
See the Administration > High Availability > Servers in the server GUI
to change the public endpoint of a server.
THIS AGENT WILL WAIT UNTIL ONE OF ITS SERVERS BECOMES REACHABLE!


---------------------------------------------------

Note that the server listening on 7085 actually DOES get registration requests:
