      Description

      I am testing ActiveMQ 5.5 with my own stress test. I tried to implement a stress test that use jms ressource in the same fashion that my application would do.

      For that, I used jms template (from Spring) and a pooled connection factory (as recommended). I run a fixed number of thread that plublish on fixed number of topics. Each thread pick up a topic and enter a loop that will send a message on the choosen topic.

      The issue is reproductible with SimpleAuthenticationPlugin active.

      Configuration of the test :

      • 100 topics
      • more than one thread per topic (actually 1500 producer threads)

      Common connection properties :

      • alwaysSessionAsync=false
      • dispatchAsync=false
      • optimizeAcknowledge=true
      • socketBufferSize=131072&trace=true&wireFormat.cacheSize=2048&wireFormat.tcpNoDelayEnabled=true&wireFormat.tightEncodingEnabled=true&keepAlive=true&soTimeout=10000&connectionTimeout=10000\

      Producers :

      • Message are not persistent
      • There is no transaction
      • Message expiration time is 30s
      • Unsing JMS template singleton with a PooledConnectionFactory
      • 3 JVM running
      • connection options alwaysSyncSend=true,copyMessageOnSend=false

      Consumers :

      • just listening to each topic with a SimpleMessageListenerContainer and count messages received
      • 3 JVM running

      In attachment, you will find activemq config file and thread dumps. I can attach the producer/consumers code if you need it but I think you have your own tests.

      This Jira is critical for me because security is mandatory for our use.

      If you need more information, please ask.
