Messages are getting stuck in activemq queue

Question

Activemq version: 5.14.3
Java version 1.7

There are 8 consumers for one queue, messages are stuck in some of the consumers.

In the above image messages are stuck in dispatched queue of first 4 consumer.
Here is my spring configuration file.

       <bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
        <property name="brokerURL" value="failover:(tcp://localhost:61616,tcp://localhost:61617)?randomize=false"/>
    </bean>

    <bean id="cachingFactory" class="org.springframework.jms.connection.CachingConnectionFactory">
        <property name="targetConnectionFactory" ref="connectionFactory"/>
    </bean>

    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
        <property name="connectionFactory" ref="connectionFactory"/>
        <property name="defaultDestinationName" value="queue/WebHookProcessingQueue"/>
    </bean>

    <bean id="myMessageSender" class="com.omoto.jms.sender.MyMessageSender">
        <property name="jmsTemplate">
            <ref bean="jmsTemplate"/>
        </property>
    </bean>

  <bean id="responseJsonMessageListenerContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
        <property name="connectionFactory" ref="cachingFactory"/>
        <property name="destinationName" value="/queue/ResponseJsonProcessingQueue"/>
        <property name="concurrentConsumers" value="8"/>
        <property name="messageListener" ref="responseJsonServiceListner"/>
    </bean>

I am new to activemq, please help me to solve this problem.

We had similar issue with CachingConnectionFactory with DefaultMessageListenerContainer, the issue is resolved after removing the CachingConnectionFactory from DefaultMessageListenerContainer. Alternatively you can disable consumer caching from CachingConnectionFactory . Refer this thread for more info Why DefaultMessageListenerContainer should not use CachingConnectionFactory? .
