I am facing a problem with QNAM when using the following request class:
=================================================request.h:=================================================class Request: public QObject{    Q_OBJECTpublic:    Request();    ~Request();    void func_startRequest(); private:    QNetworkAccessManager *manager;    QNetworkReply *reply;    QUrl url;  public slots:    void slot_requestFinished();

=================================================request.cpp:=================================================#include "request.h" Request::Request(){    manager=new QNetworkAccessManager(this);    reply=0;} Request::~Request(){    if(manager!=0){        manager->deleteLater();    }    if(reply!=0){        reply->deleteLater();    }} void Request::func_startRequest(){    QNetworkRequest request;    request.setUrl(QUrl("http://qt-project.org/"));     reply=manager->get(request);     connect(reply, SIGNAL(finished()), this, SLOT(slot_requestFinished()));} void Request::slot_requestFinished(){    disconnect(reply,SIGNAL(finished()),this,SLOT(slot_requestFinished()));     /*QNetworkSession session(manager->configuration());    session.close();    session.stop();    reply->abort();    reply->close();     reply->deletelater();    manager->deleteLater();    I have tried all of this methods, nothing shut down the threads */}
My problem is that, whenever I call manager->get(), this spawns 3  processess, which I am unable to shut down. After a while (running many requests) there were a huge amount of running processess and open file descriptors. They are consuming RAM and running out of max open file descriptor limit...Every time I call manager->get(request) 3 new processess are spawnt. 
I am using Qt 4.8.4 on Debian 5.
I have also checked the bugtracker and have found a few closed reports:https://bugreports.qt-project.org/browse/QTBUG-20148https://bugreports.qt-project.org/browse/QTBUG-20851
