Restart of JBoss fails on Solaris with BindException: Address already in use

Issue

• We frequently receive java.net.BindException: Address already in use exceptions when restarting JON and JBoss on Solaris 10
• After JON or JBoss are stopped, we must wait a few minutes before we can start them up
• Why are the listening ports not being released immediately after shutdown?
• Restart of JON Agent is delayed due to:

FATAL [main] (org.rhq.enterprise.agent.AgentMain)- {AgentMain.start-failure}Failed to start the agent

• The java process for the agent/JBoss server does not show up in the ps output, but the listening port still shows up in the netstat output.
