Hi,
I'm just testing .net C# client especially failover mode and I found
somethink disquieting. Memory usage is growing very fast when I'm
connecting to broker and disconnecting 10times per second and always
after connection send one message on topic.
I'm using broker version 5.4.2 and client 1.4.1.
connection code
1. public void AmqConnect()
2. {
3. if (string.IsNullOrEmpty(AmqUrl)) throw new
ApplicationException("AmqUrl null or empty");
4. if (string.IsNullOrEmpty(AmqQue)) throw new
ApplicationException("AmqQue null or empty");
5. MyFactory = new ConnectionFactory(AmqUrl);
6.
7. {
8. try
9. {
10. MyConnection = MyFactory.CreateConnection() as Connection;
11.
12. if (MyConnection != null)
13. {
14. MyConnection.AsyncSend = true;
15. MyConnection.AsyncClose = true;
16. MyConnection.AcknowledgementMode =
AcknowledgementMode.AutoAcknowledge;
17. MyConnection.ProducerWindowSize = 1024000;
18. MyConnection.SendAcksAsync = true;
19. MyConnection.ExceptionListener +=
ConnectionExceptionListener;
20. Mysession = MyConnection.CreateSession() as Session;
21.
22. if (Mysession != null)
23. {
24. MyDestination = Mysession.GetTopic(AmqQue) as
ActiveMQDestination;
25.
26. MyProducer =
Mysession.CreateProducer(MyDestination) as MessageProducer;
27. if (MyProducer != null) MyProducer.DeliveryMode =
MsgDeliveryMode.NonPersistent;
28. MyConsumer =
Mysession.CreateConsumer(MyDestination) as MessageConsumer;
29.
30. if (MyConsumer == null)
31. {
32. Mysession.Dispose();
33. MyConnection.Dispose();
34. Er = "Error:AMQ Consumer nullable.";
35. return;
36. }
37.
38. while (MyConsumer.ReceiveNoWait() != null)
39. {
40. }
41.
42. MyConsumer.Listener += OnMassage;
43. MyConnection.Start();
44. }
45. else
46. {
47. MyConnection.Dispose();
48. Er = "Error:AMQ Session nullable.";
49. }
50. }
51. else
52. {
53.
54. Er = "Error:AMQ Connection nullable.";
55. }
56. }
57. catch (Exception ex)
58. {
59. Er = "Error:AMQ Connection Error.";
60. if (AmqClientStatusError != null) AmqClientStatusError("AMQ
Error:" + ex);
61. }
62. }
63. }
Sending message
1. public void Send(object o)
2. {
3. (new MySendDelegate(MySend)).BeginInvoke(o, null, null);
4. }
5.
1. public void MySend(object o)
2. {
3. try
4. {
5. if (Mysession != null)
6. {
7. ActiveMQMessage request =
Mysession.CreateObjectMessage(o) as ActiveMQObjectMessage;
8. if (MyProducer != null)
9. {
10. if (request != null)
11. {
12. MyProducer.Send(request);
13. if (AmqClientStatusDebug != null) AmqClientStatusDebug("Object
sent:" + o);
14. }
15. }
16. }
17. }
18. catch (Exception ex)
19. {
20. if (AmqClientStatusError != null) AmqClientStatusError("AMQ
Error:" + ex);
21. }
Closing:
1. public void Close()
2. {
3. try
4. {
5. if (MyProducer != null)
6. {
7. MyProducer.Dispose();
8. }
9. if (MyConsumer != null)
10. {
11. MyConsumer.Listener -= OnMassage;
12. MyConsumer.Close();
13. }
14.
15.
16. if (MyConnection != null)
17. {
18. if (MyConnection.IsStarted)
19. MyConnection.Stop();
20. MyConnection.Close();
21. MyConnection.ExceptionListener -=
ConnectionExceptionListener;
22.
23.
24. }
25. }
26. catch (Exception ex)
27. {
28. if (AmqClientStatusError != null) AmqClientStatusError("AMQ
Error:" + ex);
29. }
30. }
I'm using it 10times per second with failover url. Timer in windows
forms applications use method colse then connect and send one message.
But connections are not close correctly and consume of memory is growing
FAST!
Am I doing something wrong or is a bug?
Regards,
Adam
