AMQ data dir not cleaning up even after messages getting consumed.
------------------------------------------------------------------

                 Key: AMQ-3424
                 URL: https://issues.apache.org/jira/browse/AMQ-3424
             Project: ActiveMQ
          Issue Type: Bug
          Components: Message Store
            Reporter: Hariharan


Hi,
We are using ActiveMQ 5.3 (in UNIX) and use both queues and topics (durable and 
non-durable).
The messages are published by the publishers in persistent delivery and auto 
acknowledge mode.

I can see that the consumers are actively able to consume the messages. 

However, even after the messages getting consumed successfully, the data dir 
size is not coming down. 

I tried :
 1. Using both amqPersistenceAdapter and kahaDB.
 2. Upgrading the AMQ to 5.5

But none of them is bringing down its size.

snapshot:
{code:xml} 
*After starting the broker.*

du -h activemq_data_kahadb ; ls -l /activemq_data_kahadb
48K     /activemq_data_kahadb
total 44
-rw-rw-r-- 1 manih manih 9961472 Jul 29 05:06 db-1.log
-rw-rw-r-- 1 manih manih   12288 Jul 29 05:06 db.data
-rw-rw-r-- 1 manih manih   12304 Jul 29 05:06 db.redo
-rw-rw-r-- 1 manih manih       0 Jul 29 05:04 lock

*After messages getting delivered.*

du -h /activemq_data_kahadb ; ls -l /activemq_data_kahadb
1.7M    /activemq_data_kahadb
total 1652
-rw-rw-r-- 1 manih manih 9961472 Jul 29 05:24 db-1.log
-rw-rw-r-- 1 manih manih  364544 Jul 29 05:24 db.data
-rw-rw-r-- 1 manih manih  332416 Jul 29 05:24 db.redo
-rw-rw-r-- 1 manih manih       0 Jul 29 05:04 lock
{code} 

Here are my config details:
{code:xml} 
<amq:persistenceAdapter>
    <amq:kahaDB directory="activemq_data_kahadb" journalMaxFileLength="10mb"/>
</amq:persistenceAdapter>

<amq:systemUsage>
    <amq:systemUsage>
        <amq:memoryUsage>
            <amq:memoryUsage limit="20 mb"/>
        </amq:memoryUsage>
        <amq:storeUsage>
            <amq:storeUsage limit="1 gb"/>
        </amq:storeUsage>
        <amq:tempUsage>
            <amq:tempUsage limit="100 mb"/>
         </amq:tempUsage>
    </amq:systemUsage>
</amq:systemUsage>
{code} 

I do understand that the messages are persisted until consumed by the 
consumers, but after that shouldn't the file size be coming down?
Please let me know if there are any config changes that I need to do to get 
this working fine.

Thanks in advance
Hari
