Even, I stop the market data publishing, the CPU usage of ActiveMQ broker is still eat up 50%, cannot drop for a long time and NO error/warning log recorded in activemq.log. When I remove redeliveryPlugin and socketBufferSize from Broker (activemq.xml), it resume normal. Please help to solve. Also, how to show redelivery message in log when occur, thanks.
