Subject [jira] [Updated] (AMQ-4715) Memory issue with ActiveMQ in java
Date Mon, 09 Sep 2013 22:02:52 GMT

     [ https://issues.apache.org/jira/browse/AMQ-4715?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Timothy Bish updated AMQ-4715:
------------------------------

    Description: 
Every time when i start connection and create session i can see “java.exe” (in task manger)
memory get increase by 1000 to 2000K that’s ok.
Now, when i closed connection and session expecting to memory  go down by 1000 to 2000K but
nothing happening.

Here is my sample code.

{code}
public static void main(String[] args) {

  try {
    ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616");
    Connection connection= connectionFactory.createConnection();
    connection.start();          

    for(int i=0;i<40;i++) {
      Session session=  m_connection.createSession(false, Session.CLIENT_ACKNOWLEDGE);
      Destination queueDestination = session.createQueue("TestQueue");

      MessageProducer producer = session.createProducer(queueDestination);
      producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);

      TextMessage textMessage = session.createTextMessage();
      textMessage.setText(“some text”);

      String jmsCorrelationId= UUID.randomUUID().toString();
      textMessage.setJMSCorrelationID(m_jmsCorrelationId);
      producer.send(textMessage);

      if (producer != null) {
         producer.close();
         producer=null;
      }
      
      if(m_session != null) {
        session.close();
        session=null;
      }
    } // end for loop

    if (connection!=null) {
      connection.close();
    }
  }
}
{code}

If you will execute this program three to four times you will see significant memory get increase
in task manger for “java.exe”.
Thing most bothering me is that… after executing this program all allocated memory should
get cleaned-up by GC but look like somehow it’s not happening.

No idea what am I doing wrong?

Please help me!
