• When syncing agent from JBoss ON UI, the operation always fails with below error message, But using agent command line ">inventory -s" doesn't generate the error:

java.lang.RuntimeException: Call to [org.rhq.plugins.agent.AgentServerComponent.invokeOperation()] with args [[executePromptCommand, Configuration[id=16985]]] was rudely interrupted.
