           Summary: QTwebkit memory consumption
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Blocker
          Priority: P2
         Component: WebKit Qt
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: rmorgade at arantia.com


We fave developed a webbrowser on top of QT for an embedded linux platform. There is 256MB available to the linux kernel, on startup there's almost 140MB free but as you load different URIs into the browser, the memory keeps growing until wraps all the available memory. Then the oom killer usually kills the process or the system must be reboot.

We have made a minimum webbrowser which loads continuosly the same webpage:

#include <QWebView>
#include <QtGui>

class Loader : public QObject {
    Q_OBJECT
public:
    Loader(QWebView* view, const QUrl& url) : m_view(view), m_url(url) {}

public slots:
    void loadNext()
    {
        m_view->load(m_url);
    }

private:
    QWebView* m_view;
    QUrl m_url;
};

#include "main.moc"

int main(int argc, char **argv)
{
    QApplication application(argc, argv);
    QWebView view;
    QUrl url("http://www.webkit.org");
    Loader loader(&view, url);
    QObject::connect(&view, SIGNAL(loadFinished(bool)), &loader,
SLOT(loadNext()));
    view.load(url);
    view.show();

    return application.exec();
}

This have been tested with:

- Qt versions : 4.7.2 / 4.8.1 /4.8.4
- Platforms : x86 / mipsel

The process used memory increments itself per interation in amounts of ~4KB.

I have seen several issues like this reported and throughout the internet even from years ago, but I wasn't able to find a solution. So our browser, that is ment to be used in a long run app ( IPTV middleware ) is useless right now.
