    SimpleMemoryManager Warning

    DENNIS CREEDEN Newbie

      Hi again,

      The JBoss Messaging system is working great. Performance is outstanding and memory usage is negligible even with 400K messages. Memory usage for the whole application never exceeds 50M.

      My only question is that I get a series of these warning messages:


      13:46:03,093 WARN [SimpleMemoryManager] Less than 25% of total available memory free
      13:46:05,109 WARN [SimpleMemoryManager] Less than 25% of total available memory free
      13:46:07,109 WARN [SimpleMemoryManager] Less than 25% of total available memory free
      13:46:09,140 WARN [SimpleMemoryManager] Less than 25% of total available memory free
      13:46:11,140 WARN [SimpleMemoryManager] Less than 25% of total available memory free
      13:46:13,140 WARN [SimpleMemoryManager] Less than 25% of total available memory free
      13:46:15,156 WARN [SimpleMemoryManager] Less than 25% of total available memory free

      It doesn't seem to affect anything.

      Is it a configuration setting, should I be flushing the queues or what?

      The dilivery mode is DeliveryMode.NON_PERSISTENT and there is only one message consumer. Once the consumer gets the message I want the message removed from the queue. Am I missing something?

      Thanks for your help.

      Dennis

          Glad to hear it :)
          FYI the next release (1.0.1.RC4) which will be out very soon has some very significant further increases in performance.

          You probably just need to increase your -Xmx setting for the server a bit. (in run.bat)
