Description

If the WIFI network changes often it leads to a memory leak, because the network service is not deleted on change:

void QNetworkSettingsManagerPrivate::handleNewService(const QString &servicePath)

creates the service:

QNetworkSettingsService *service = new QNetworkSettingsService(servicePath, this);

and expects it to be only deleted when QNetworkSettingsManager is destroyed.

Possible workaround can be:

bool QNetworkSettingsServiceModel::removeService(const QString &id)
{
    bool ret = false;
    for (int i=0; i < m_items.count(); i++) {
       if (m_items.at(i)->id() == id) {
           // workaround
           m_items[i]->deleteLater();
           // workaround end
           remove(i);
           ret = true;
           break;
       }
    }
    return ret;
}
