Subject QueueSize and InFlightCount on a Topic keeps growing
Date Mon, 14 Jul 2008 15:17:29 GMT
I have a non-persistent Topic with a single producer (Java-JMS) and 
multiple non-durable consumers (written in C# NMS)

Looking at the Topic in jconsole I notice the following:

   1. The QueueSize on the Topic is the same as the EnqueueCount  and
      keeps increasing with each new message.
   2. The InFlightCount stays around zero for a while, but then starts
      to increase (the value being the difference between DequeueCount
      and DispatchCount
   3. Eventually the consumers stop receiving any new messages.

Can anyone explain what these various values represent and what might be 
causing this behaviour?

I'm using ActiveMQ 5.0
