HornetQ pending messages

Solution Verified - Updated -

Environment

  • Red Hat JBoss Enterprise Application Platform (EAP)
    • 5.1.2
  • HornetQ
    • 2.2.x

Issue

  • The messages were still stuck in the topic even after the messages were consumed by the durable subscribers.

Resolution

  • The client was creating transacted session using the following code without acknowledging after the message was consumed.
 TopicSession topicSessionPublish = topicConnPublish.createTopicSession(false, Session.CLIENT_ACKNOWLEDGE)
  • You either need to acknowledge the message from the client by calling 
message.acknowledge();
  • Or by letting the acknowldgement be handled by the container using the following code:
 TopicSession topicSessionPublish = topicConnPublish.createTopicSession(false, Session.AUTO_ACKNOWLEDGE);
