Subject [jira] [Commented] (AMQ-4533) Messages stuck in queue with redelivered=true
Date Wed, 18 Sep 2013 16:48:57 GMT

    [ https://issues.apache.org/jira/browse/AMQ-4533?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13770952#comment-13770952
] 

Timothy Bish commented on AMQ-4533:
-----------------------------------

Idle consumers are consumers that have no outstanding dispatched messages.  These consumer
have nothing to do and therefore would always trip the slow condition and eventually be closed.
 In the case of having the abortConnection=true this means that you'd have consumer connection
coming and going for no real reason which could impact performance of your application.  I
don't see why you'd want to not just ignore the idle one's and only focus on consumers that
have not ack'd outstanding messages in the allocated time.

> We're  getting message stuck in queues with the 
> redelivery flag set to true.
> We used the following test model: put every 1 second 50 messages sequentially, and after
that, the rest of 1000 msgs quickly to INPUT_QUEUE and 
> while starting 25 listeners cosuming from INPUT_QUEUE, which takes about 30 seconds to
move the message to RECEIPT_QUEUE, 10 other listeners on RECEIPT_QUEUE consume and counts
them.
> We tried making one of the consumer slow by setting the 
> processing time to 100000 seconds (sleep) and putting a heavy load in 
> 500 threads every 1 ms to some other queues the same time.
> Our test case is attached, you might need to install some dependencies 
> to the local maven repository manually:
>      mvn install:install-file -DgroupId=org.apache.activemq 
> -DartifactId=activemq-core -Dversion=5.7.0-fuse-71-047 -Dpackaging=jar 
> -Dfile=activemq-core-5.7.0.fuse-71-047.jar
>      mvn install:install-file -DgroupId=org.apache.kahadb 
> -DartifactId=kahadb -Dversion=5.7.0-fuse-71-047 -Dpackaging=jar 
> -Dfile=kahadb-5.7.0.fuse-71-047.jar
>      mvn install:install-file 
> -DgroupId=org.apache.geronimo.management.specs 
> -DartifactId=geronimo-j2ee-management_1.1_spec -Dversion=1.0.1 
> -Dpackaging=jar -Dfile=geronimo-j2ee-management_1.1_spec-1.0.1.jar
>      mvn install:install-file -DgroupId=org.apache.activemq.pool 
> -DartifactId=activemq-pool -Dversion=5.7.0-fuse-71-047 -Dpackaging=jar 
> -Dfile=activemq-pool-5.7.0.fuse-71-047.jar
> To run the test, simply use the Maven test target:
>     mvn clean test
> If the problem occurs the you'll get a message like this in the test 
> results, (target/surefire-reports):
>     java.lang.AssertionError: Still messages in InputQueue expected:<0> 
> but was:<365>
