you are using ActveMQ classic, right? Please provide the version. 5.17.4
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? No I am not
What platform are you running on? Red Hat Enterprise 8.7
How many clients did you connect? There is one broker instance and 3 consumers \
connected

Betreff: [Ext] Activemq heap space issues
________________________________
Hello I am troubleshooting actviemq and I am getting memory errors. 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. \
Thanks for any help you can provide.
