<transportConnector name="openwire" uri="tcp://0.0.0.0:61618?maximumConnections=1000&wireFormat.maxFrameSize=857600"/> Then I start the broker and use the console to send messages activemq:producer --user admin --password admin --messageSize 850000 --messageCount 10 it works, but it error out when I push for 1mb message through activemq:producer --user admin --password admin --messageSize 1850000 --messageCount 10 here is the infinite loop goes when you observe the log:tail.
