             Summary: Messages are stuck in a Queue that is configured on HornetQ
                 Key: WFLY-9639
                 URL: https://issues.jboss.org/browse/WFLY-9639
             Project: WildFly
          Issue Type: Bug
          Components: Application Client
    Affects Versions: 9.x.x TBD
         Environment: RHEL 7.2, JDK 1.8_144
            Reporter: Rajendra Mallampati
            Assignee: Stuart Douglas


We use WildFly 9.0.2 for hosting our web application and it has both real time and batch processing components. One of the functions supported on the web includes uploading a file with a number of lines any where from 1 to 10K, If the file is valid (virus scan etc passed) it is parsed into that may messages and published to a queue. Each message will have two counters total number of messages that are published to the queue, and the message number. 
The consuming side is implemented using Spring DefaultMessageListenerContainer (DMLC) with a concurrency of 50 and maxConcurrency of 75. The listeners that implement MessageListener interface are integrated into DMLC. sometimes, if the producing side published 100 messages the consuming side only receiving 98 (per say) and gets stuck because two more messages should be in the Queue. Those two messages are not delivered and don't know where they are going. We tried even persistent Queues and the result is same (getting stuck).
This is happening in production and any insight into this issue is highly appreciated.

Here are the software details:
App server : Wildfly 9.0.2
HornetQ : 2.4.7
JDK : 1_8_144

If you need additional details I will be very glad to provide.

Thanks
Rajendra
