             Summary: Queue#MessageCount negative and messages stop flowing to AMQP consumer
                 Key: ARTEMIS-1982
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-1982
             Project: ActiveMQ Artemis
          Issue Type: Bug
    Affects Versions: 2.5.0
            Reporter: Keith Wall


I am running performance tests against EnMasse which current uses Artemis 2.5.0.   Many millions of messages have traversed the Broker (all AMQP protocol).

 

I have encounter a situation where messages have stopped flowing to the AMQP consumer.  On inspection of the Artemis console, I notice that statistics including the MessageCount have gone negative (-99). 

One in this state, I notice if I produce one message  then attach a consumer, no message flows.  However if add two messages to the queue, the consumer gets only the 2nd message.

 

bash-4.2$ curl --user admin:admin -k [https://localhost:8161/console/jolokia/read/org.apache.activemq.artemis:broker=%22broker-0%22,component=addresses,address=%22queue%22,subcomponent=queues,routing-type=%22anycast%22,queue=%22queue%22]
