snert:/im/rhq/modules/enterprise/agent/target/rhq-agent hrupp$ bin/rhq-agent.shListening for transport dt_socket at address: 8788 RHQ 4.4.0-SNAPSHOT [74326f0] (null) The server has rejected the agent registration request. Cause: [org.rhq.core.clientapi.server.core.AgentRegistrationException:An agent is trying to register with an existing agent name [snert] without providing a valid security token. If you are attempting to re-register this agent, please consult an administrator to reconfigure this agent with its proper security token.] Will retry the agent registration request soon... Neither this, nor rhq-agent.sh --help tells me the magic -Dx=y combination to pass the token in - I think this is not user friendly. We should either in that message list the property name - or on the server page that lists the token, so that a user that runs into that issue can easily fix it without googling etc.

the error messages are build in CoreServerServiceImpl - so any changes would go in there
git commit 5745929 message will now say: An agent is trying to register with an existing agent name [snert] without providing a valid security token. If you are attempting to re-register this agent, please consult an administrator to obtain the agent's proper security token and restart the agent with the option "-Drhq.agent.security-token=<the valid security token>"
Bulk closing of items that are on_qa and in old RHQ releases, which are out for a long time and where the issue has not been re-opened since.
