Hi Attila, the QueueControl.browse management method is not designed to be used with such a big number of messages at a time. It was designed to provide the browse feature to the web console that browses 10 messages at a time. I would recommend using a JMS client to browse such a big number of messages, i.e. https://github.com/apache/activemq-artemis-examples/tree/main/examples/features/standard/browser
