[Franco NG (JIRA)]

Franco NG created AMQ-7190:
------------------------------

             Summary: ActiveMQ cannot handle too many topic with 
redeliveryPlugin
                 Key: AMQ-7190
                 URL: https://issues.apache.org/jira/browse/AMQ-7190
             Project: ActiveMQ
          Issue Type: Improvement
          Components: Broker
    Affects Versions: 5.15.8
            Reporter: Franco NG
             Fix For: 5.15.8
         Attachments: activemq.xml

Our market data would publish over 20,000 msg/s within 30,000 topics, 
redeliveryPlugin and socketBufferSize, however, ActiveMQ seems unable to handle 
this volume that CPU usage % is 50% and cannot publish any message to 
subscriber(s) after certain starting time.  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.
