Increase in memory when using QMetaObject::invokeMethod with qvarientlist

[Tirupathi Korla]

Hi,
I Have an application with table(which is in qml) which is updated every second from cpp file using QMetaObject::invokeMethod(). Each second a new qvarientlist is created and sent to qml file by using QMetaObject::invokeMethod(). I see an increase in memory. It is increasing continously and never decreasing. Could anyone give me a hint what i am missing.

Thanks & Regards

@Tirupathi-Korla Well, without seeing the code it is impossible to say why this happens...
How do you create the list? Is the list destroyed at some point?

This is the function in cpp.

   void myClass:: callBack(QByteArray ary){
            QVariantList reports;
            reports.append("test:");
            temp_report * t = ((temp_report*)(ary.data()));
            QString str = t->value;
            str.append(" $");
            reports.append(str);
            QMetaObject::invokeMethod(qmlRootObject, "callMoneyFunction",
                                      Q_ARG(QVariant, reports));
            reports.clear();
            ary.clear();
}

Below is qml code

        function callMoneyFunction(value){
            var str = sourceModel.get(0).value;
            sourceModel.remove(0)
            sourceModel.insert(0,{"key": "Amount: "  + value[0],"value":str });
        }

SourceModel is listmodel of tableview.
