Memory leak in my threaded SSL server application

[sadjoker]

Hello, i`ll watch that thread closely for your final investigation about the memory leak. I`ve got the same problem with a multithreaded QSslSocket app myself and the memory of my server app goes up like ~700kb per client connect/disconnect. And my code is similar to yours.

By the way, I am using QT version 4.6.2.

There is a reported bug about QSslSocket memory leak in the following link: http://bugreports.qt.nokia.com/browse/QTBUG-6504
I do not know whether or not this the problem I am having here.

Finally I found the code causing the memory leak:
In the server side, setting the private key causes a memory leak. It seems like a bug in QT.

The code that causes the memory leak is:

m_socket->setPrivateKey(":/certs/my-key.pem");  //  Add the key that will make the handshake
m_socket->setLocalCertificate(":/certs/my-cert.pem");

m_socket->setPrivateKey(":/certs/my-key.pem");  //  Add the key that will make the handshake
m_socket->setLocalCertificate(":/certs/my-cert.pem");
