Hi, 
I am using Liferay 6.2 CE GA6 and I have configured two Liferay Message bus listeners.It was working fine from a year almost but suddenly one of the Message Bus listener has stopped listening the messages sent by application.Following is my messaging-spring.xml file:<?xml version="1.0"?><beans default-destroy-method="destroy" default-init-method="afterPropertiesSet"

            </list>
        </property>
    </bean>
</beans>
Is there anyway where we can see the list of messages sent to a message bus orwe can track the status of messages?Can anyone please help me out in this?Thanks
