Subject [jira] [Commented] (AMQ-4533) Messages stuck in queue with redelivered=true
Date Wed, 12 Jun 2013 15:56:20 GMT

    [ https://issues.apache.org/jira/browse/AMQ-4533?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13681347#comment-13681347
] 

Gary Tully commented on AMQ-4533:
---------------------------------

from the current test case (as updated by tim) the queue depth matches the inflight count
due to messages prefetched by the consumer that waits for ever. 
This is expected. Until the waitingForever consumer closes, prefetched messages will not be
consumable. Using a prefetch of 0, so making the consumers pull messages on demand will resolve
this.

In the production env, does the destination with unexpected queue depth have an inflight value
that matches when viewed via jmx?

> 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>
