Subject ActiveConsumerCount vs ConsumerCount
Date Fri, 05 Feb 2010 13:31:34 GMT
I posted this question to the users mailing list, but received no
replies, perhaps the dev subscribers can provide some insight.

I have been running into an issue where unpredictably, my java
qpid-broker runs out of memory. I tried upgrading to 0.6 to see if it
resolved the issue, but it seems to still be present.

In an attempt to debug the problem I connected the QPID JMX Management
console to the broker. What I noticed is that when only my synapse
process was running the ActiveConsumerCount did not increase. Yet, when
my jruby JMS client was running the ActiveConsumerCount consistently
increased without ever decreasing.


  1. What does the ActiveConsumerCount represent?

  2. Is it possible that the increasing of the ActiveConsumerCount is
     causing the broker to exhaust its memory?

  3. What might be the reason my jruby JMS process is causing this value
     to increase?

thanks, Jesse
