Timothy Bish commented on AMQ-4715: ----------------------------------- You'd need to do more analysis on your code / app before blaiming activemq, use a tool like yourkit to look at the usage of you app. > Memory issue with ActiveMQ in java > ---------------------------------- > > Key: AMQ-4715 > URL: https://issues.apache.org/jira/browse/AMQ-4715 > Project: ActiveMQ > Issue Type: Bug > Affects Versions: 5.6.0, 5.7.0 > Reporter: ritesh > > 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! -- This message is automatically generated by JIRA.
