[jira] [Commented] (AMQ-2870) Messages that don't match a message
selector for a durable subscription are stored causing the persistent store
to eventually fill up
[ https://issues.apache.org/jira/browse/AMQ-2870?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13467600#comment-13467600 ]
Lars Hvile commented on AMQ-2870:
---------------------------------
This error still exists when using the JDBC store..
2012-10-02 11:55:57,299 | TRACE | ignoring unmatched selector ack for: ID:java-dev-image-37369-1349171756956-0:1:1:1:1, cleanup will get to this message after subsequent acks. | org.apache.activemq.store.jdbc.JDBCTopicMessageStore | ActiveMQ Transport: tcp:///127.0.0.1:34884
The cleanup will of course never get to this message, as no messages are acked ever..
This exclusion of unmatched selectors happens at
https://fisheye6.atlassian.com/browse/activemq/trunk/activemq-core/src/main/java/org/apache/activemq/store/jdbc/JDBCTopicMessageStore.java?r=1345202#to73
It was introduced as a fix to some other bugs in https://fisheye6.atlassian.com/changelog/activemq?cs=1025939

> With a durable sub, ack entries are created on a message send for each durable sub, but if the durable sub does not match the message due to a selector, the message remains unacked, pending, such that is can fill up the store. Any unmatched message should be acked immediately.
