Gary Tully commented on AMQ-3736:
---------------------------------
To get the unused topics cleaned up, see:
http://activemq.apache.org/delete-inactive-destinations.html
Note: that the index file(db.data) will not shrink, but should stabilize one
the maximum is reached. The db.data file is a collection of data pages that can
get reused once they are free, but unused destinations will need to be deleted
if they are created at runtime.
> Kaha DB Db.data file is growing

> Key: AMQ-3736
> URL: https://issues.apache.org/jira/browse/AMQ-3736
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.5.1
> Environment: cent os 5.3, java 6 update 30
> Reporter: Krishnadasan T S
> Priority: Blocker
> Attachments: activemq.xml
>
>
> In our production and development environment db.data file is growing. Within
> few weeks it reaches GB's in size. When it grows larger broker hangs
> frequently. I have already reported a bug in 5.4.2(AMQ-3710) url
> https://issues.apache.org/jira/browse/AMQ-3710. In that case db.data had a
> size of 5 GB. When we cleared kaha db related files db.data,db.redo and
> db-735.log files, that issue solved.By further monitoring We noticed that
> db.data file is growing by day from MB to GB. And when the size become
> larger, the broker hanging issue is coming back.
> Now we have updated Our activemq broker to 5.5.1. But db.data is
> still growing. Every day we are monitoring it and if it is become big(200 mb)
> we are clearing all kaha related files before our business start.
> Other kaha related files are normal. db-*.log files are cleared by kaha db.
> db.redo file is not growing. Only db-data file is growing.
> I don't think this is a correct behavior. At certain point of time it
> should clear unwanted data write. I am using the same configuration without
> much change.
> I have attached active mq config file with this.
