Question about "Negative Pending Messages"

[weit <we...@yahoo.com>]

Hi all,

I'm running a network of 2 ActiveMQ brokers (ActiveMQ 5.1 btw) and my
producers are sending quite a number of messages (~300 to 500 messages per
second).  Consumers are relative fast as well in handling the messages.

However, I noticed that there are negative values in the Pending Messages
field when I access the web console admin page.

So my question is what does the negative value stand for and how should I
deal with them?

Thanks in advance!

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.
