re: Integration - Bridging Microsoft MSMQ and IBM WebSphere MQ on 64-bit Windows

Hi, Hope to get help from you.

We implement a messaging systems. The server receives message from clients and stores it in MSMQ. It then forward the message to another destination. The program of routing message first enable the MSMQ: MQAutoReceive(q2)

MQAutoReceive (MessageQueue objQName, //) {...//

//......

objQName = new MessageQueue(".\\Private$\\" + qNameToPtTo);

objQName.Formatter = new XmlMessageFormatter(new Type[] { typeof(byte[]) });

objQName.ReceiveCompleted += new ReceiveCompletedEventHandler(nameOfHandler);

objQName.UseJournalQueue = useJournal;

objQName.MessageReadPropertyFilter.ArrivedTime = true;

objQName.BeginReceive();

//......}

The handler of completed message receiving like this:

q2ReceiveCompleted(object p_source, ReceiveCompletedEventArgs p_objAsyncResult)

{

//..........

try{

q2 = ((MessageQueue)(p_source));

m2 = q2.EndReceive(p_objAsyncResult.AsyncResult);

if (m2.ArrivedTime.AddSeconds(msgValidity) < DateTime.Now)

{

q2.Refresh();

q2.BeginReceive();

return;

}

m2.TimeToReachQueue = new TimeSpan(0, 0, TIME_TO_REACH_Q);

m2.AdministrationQueue = q2AdminQ;

m2.AcknowledgeType = AcknowledgeTypes.FullReachQueue;

m2.UseJournalQueue = true;

//.........................

}

catch {

}

finally {

q2.Refresh();

q2.BeginReceive();

}

We have very serious problem of memory leaking. We dont really comprehend it as the message in queue is removed (EndReceive), but still memory is growing.

Hope to get help from you.

Thank you.

Hi Jimmy,

I regret to say that this one slipped through the net and I've only just found it - non-anonymous comments are automatically accepted.

Did you get to the bottom of the problem?

Cheers
