Hello Brian, you are using ActveMQ classic, right? Please provide the version. The management console is there in this case, yes but I did not find it very useful, that's right. To monitor memory etc. the JMX interface together with JVisualVM is the real hit in this case. Are you familiar with this tool? What platform are you running on? How many clients did you connect?

I am trying to determine the best way to investigate how to mitigate these errors by adjusting the settings. Is there documentation on troubleshooting memory issues? I am able to view the web console and I see a bunch of messages in the queue but not really much else.
