Subject [jira] [Created] (AMQ-5433) AMQP messages stuck in broker when receiver detaches while receiving
Date Wed, 12 Nov 2014 18:32:33 GMT
Chuck Rolke created AMQ-5433:
--------------------------------

             Summary: AMQP messages stuck in broker when receiver detaches while receiving
                 Key: AMQ-5433
                 URL: https://issues.apache.org/jira/browse/AMQ-5433
             Project: ActiveMQ
          Issue Type: Bug
          Components: AMQP
    Affects Versions: 5.11.0
         Environment: broker: snapshot apache-activemq-5.11-20141022.222801-124-bin.tar.gz
Wed Oct 22 22:28:02 UTC 2014
host: Linux Fedora 19 x64
client: Amqp.Net Lite self tests
            Reporter: Chuck Rolke


[Amqp.Net Lite|https://amqpnetlite.codeplex.com/] has a set of self tests that work OK when
run against a Qpidd 0.30 (proton 0.8) broker. However, when run against ActiveMQ 5.10 or 5.11
SNAPSHOT one self tests causes a batch of messages to get stuck in the broker.
The self test in question is [LinkTests.cs CloseBusyReceiver|https://amqpnetlite.codeplex.com/SourceControl/latest#test/Test.Amqp.NetMF/LinkTests.cs].

The test 
* opens a sender and receiver to node q1.
* sends 20 messages. 
* when the receiver receives the first message it closes the receiver and that causes an AMQP
detach. 
* then the test opens a second receiver and tries to drain the 20 messages.
The test fails because the second receiver never receives anything. The AMQ web console shows
the 20 messages in the queue. 

Running the test again without clearing the queue results in 40 messages in the queue and
the self test fails because the first receiver never receives any messages and thus never
closes the busy receiver. The first 20 messages jam that queue.

Also, the messages are not received by tools that normally work fine, like qpid-receive.

This effect is 100% repeatable.
