> -----------------------------------------------------------------------------
>
> Key: AMQ-3961
> URL: https://issues.apache.org/jira/browse/AMQ-3961
> Project: ActiveMQ
> Issue Type: Bug
> Components: Connector
> Affects Versions: 5.6.0
> Environment: Default configuraton of ActiveMQ under Linux or Windows
> Reporter: Andreas Mattes
> Attachments: PrefetchSubscription.patch,
> PrefetchSubscriptionTest.java, TestClient.java
>
>
> A durable subscriber is connected to ActiveMQ using the ConnectionConsumer
> protocol, transacted sessions, and at most 1 message per session. While the
> subscriber is disconnected, the publisher publishes e.g. 10 messages. When
> the subscriber re-connects, it only receives 2 messages of those. If it
> repeatedly disconnects and re-connects, it receives 2 messages each time
> until all messages are received.
> Further investigation reveals that the problem lies in class
> org.apache.activemq.broker.region.PrefetchSubscription which does not
> re-check for further pending messages to be dispatched when committed message
> are removed from the list of dispatched but not yet acknowledged messages.
