Gary Tully commented on AMQ-6671:
---------------------------------
[~anujkhandelwal90] it may be that the cleanup task needs to run a few times.
messages for durable subs that are unreferenced are deleted periodically with
the cleanupPeriod which defaults to 5mins. Then there is an iteration per each
priority 1-10, messages with default priority 4 may take 20mins to clear by
default
> ActiveMQ with PostgreSQL: Not deleting persistent messages sent to a topic
> ---------------------------------------------------------------------------
>
> Key: AMQ-6671
> URL: https://issues.apache.org/jira/browse/AMQ-6671
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker, JDBC
> Affects Versions: 5.11.1
> Reporter: Anuj Khandelwal
>
> Using ActiveMQv5.11.1
> I ran a test case where a durable subscriber was listening from a topic and a
> publisher is publishing persistent messages. I observed that the messages
> were stored in the DB (ACTIVEMQ_MSGS table) but even after successful
> consumption by the consumer, these messages were not deleted from the backend
> DB. However I have seen that this doesn't happen in case of queue. Persistent
> messages sent to a queue are automatically deleted from the DB once
> successfully consumed by the consumer.
> More details:
> 1. 1 producer 1 durable subscriber. Subscriber is in auto_ack mode.
> 2. Producer sent 100 persistent messages to consumer
> 3. Consumer successfully consumed them.
> 4. DB still has those messages.
> 5. Stop producer and consumer both, but messages are still there.
> 6. Even after restarting broker, message does not get deleted.
> This is a very generic use case which should never happen. It is also
> reproducible.
> Thanks,
> Anuj
