> 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

> 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
