Juraj Kuruc commented on AMQ-1797:
----------------------------------
I've tested amq revision number 747951. Cleaning storage using
amqPersistenceAdapter is better now, but there are still files that, in my
opinion, need to be deleted - in data/journal/ directory after receiving sotps
there are still files data-47 and data-87 and no other number between (I guess
that in optimal state should be file numbering continous).
There is also problem that from 100k msgs sent message have been only 97208
acknowledged (it should be 100k on both receivers, while every odd message is
ack) and "already dispatched" error is still there.
with kahaPersistenceAdapter is behaviour very similar as before.
> persistent messages for durable subscribers are not purged from disc storage

> Project: ActiveMQ
> Issue Type: Bug
> Components: Message Store
> Affects Versions: 5.1.0
> Environment: WinXP,
> java version "1.6.0_05"
> Java(TM) SE Runtime Environment (build 1.6.0_05-b13)
> Java HotSpot(TM) Client VM (build 10.0-b19, mixed mode, sharing)
> Reporter: Juraj Kuruc
> Assignee: Rob Davies
> Fix For: 5.3.0

> Attachments: activemq.xml, kaha_amq.zip,
> Storage_cleanup_Redelivery_test.zip, textMessageFile.txt,
> TopicConsumers.java, TopicProducer.java

>
> I have some problems with multiple durable subscribers while persistent
> delivery is used.
> Message should be deleted from disc storage (periodically) after all
> interested subscribers have received it. In case there was one durable
> subscriber everything woks just fine. However when I tested this scenerio
> with two durable subscribers on topic, the messages were never deleted (disc
> usage is continously consumed and never purged).
> Test case description:
> -using default activemq.xml configuration file from binary distribution
> -TopicConsumers.java creates two separetes durable consumers
> -textMessageFile.txt is file which text is sent by producer (place it on
> classpath)
> Result:
> -all messages there were send were also received by both subscribers
> -after more then 100k messages data directory is about 1GB.
> -restarting activemq with so big persistent storage takes very long time
