[jira] Updated: (AMQ-1148) Fast producer, slow consumer hangs after
a few messages when using VMPendingSubscriberMessageStoragePolicy
[ https://issues.apache.org/activemq/browse/AMQ-1148?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rob Davies updated AMQ-1148:
----------------------------
Priority: Major (was: Critical)
> Fast producer, slow consumer hangs after a few messages when using VMPendingSubscriberMessageStoragePolicy
> ----------------------------------------------------------------------------------------------------------
>
> Key: AMQ-1148
> URL: https://issues.apache.org/activemq/browse/AMQ-1148
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.0.0
> Environment: Sun JDK 1.6.0 on Windows XP SP2 with VM arguments -Xms384m -Xmx512m
> Reporter: Albert Strasheim
> Assignee: Rob Davies
> Fix For: 5.0.0
>
> Attachments: SlowConsumerTest.java, SlowConsumerTest.java
>
>
> Following from this discussion:
> http://www.nabble.com/Fast-producer%2C-slow-consumer-with-spooling-to-disk--tf3123868.html
> Rob Davies implemented VMPendingSubscriberMessageStoragePolicy which, if I understand correctly, should cause a fast producer to block if a slow consumer can't keep up.
> However, when running the attached test case, the system seems to hang before the consumers have received much more than 5 messages. When it hangs probably depends on the heap size.
