Those messages must still be in the journal files. Is your checkpoint worker cleaing up the journals every 30 seconds?

There is also one topic "ActiveMQ.Advisory.Queue" which holds 7 messages. That's all. After purging "ActiveMQ.DLQ" and restarting the instance ActiveMQ brings up 23 messages in "ActiveMQ.DLQ". Except viewing the admin web page and purging the queue there was no further activity.

It's a small application which uses about seven or eight queues with about max. 1,000 small messages (tickets from a deposit machine) per queue / day. We use persistent queues via KahaDB and did not change any KahaDB parameters. With this the number of KahaDB journals (db-xxx.log) is growing every day. >From 2013/07 until now we got 439 files with the default size of 32mb, which >cumulates to about 12 gb. I copied this database to a standale ActiveMQ instance to analyze it: On startup an automatic recovery is startet which "recovers" 5,400,000 (!) entries. All queues used by our application are shown with zero entries except the ActiveMQ.DLQ (dead letter queue) with 77 entries. There are also about four or three topics shown with maximum 7 entries. While running this database on an ActiveMQ instance for 10 minutes it grows by three new files (about 95 mb). First questions: where do the 5.4 million of entries hide? How can I get rid of them without without a complete deletion of the database? How can such a state occure, and more important, how can we avoid this? -- View this message in context: http://activemq.2283324.n4.nabble.com/KahaDB-journals-growing-no-visible-entries-tp4675358.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
