Subject Re: Question about "Negative Pending Messages"
Date Wed, 20 Aug 2008 16:03:28 GMT

I think you'll also see that on the JConsole, 'queuesize' is also a negative
number that matches that on the web console. See the followign thread.

Sessions/consumers were being closed immediately after committing or
acknowledging receipt of the message. So the problem was addressed by adding
a slight delay just prior to the close. This happens when using either
commits or acks.  

Hope this helps.
