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"
   xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">      <bean id="messageListener.generalMessageListener"
       class="com.test.GeneralMessageListener" />   <bean id="messageListener.campaignExecutionListener"
       class="com.test.CampaignExecutionListener" />      <bean id="general.messages" class="com.liferay.portal.kernel.messaging.SerialDestination">

                   </list>
               </entry>
               <entry key="campaign/execution">
                   <list value-type="com.liferay.portal.kernel.messaging.MessageListener">
                       <ref bean="messageListener.campaignExecutionListener" />
                   </list>
               </entry>
           </map>
       </property>
       <property name="destinations">
           <list>
               <ref bean="general.messages" />
               <ref bean="campaign.execution" />
           </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
