> 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.equals(null))
> {
> producer.close();
>              producer=null;
> }
> if(!m_session.equals(null))
> {
>                 session.close();
>                 ession=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!
