Subject [jira] [Commented] (AMQ-3712) ActiveMQ browser shows negative message count with messages dequeued count greater than messages enqueued
Date Mon, 04 Mar 2013 18:53:14 GMT

    [ https://issues.apache.org/jira/browse/AMQ-3712?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13592497#comment-13592497

Christian Posta commented on AMQ-3712:
--------------------------------------

You might be seeing this where the enqueue/message count is a time-based counter (from when
the broker started), whereas QueueSize on a particular queue takes into account the store
regardless of time:

> It seems messages are rightly consumed but messages dequeued count is greater than messages
enqueued.
