Hi,
I recently upgraded my cms library from 3.0 to 3.1(built using vs-2005),
and face some issues that handle leaks when reconnecting to server.
So I wrote a simple testing program based on vs2005-activemq-example,
and found that it occurs even I just create the connection and close it.
Has any one encountered this before?
Or is there anything I should notice but missed?
Any reply is appreciated.
Here is the code I wrote for testing.
==============================
while(true){
ConnectionFactory* connectionFactory(
ConnectionFactory::createCMSConnectionFactory(
"tcp://127.0.0.1:61616" )
);
Connection* connection = connectionFactory->createConnection();
connection->start();
connection->close();
delete connection;
connection = NULL;
delete connectionFactory;
connectionFactory = NULL;
Sleep(2000);
}
=============================
And following are the reports generated using DebugDiag.
It's strange that it leaks in different when I using different linking
method.
