Qt 5.2.1 has a serious memory leak: https://bugreports.qt-project.org/browse/QTBUG-37578
It is fixed in 5.2.2 as shown in the bug report.
Please update Qt for Ubuntu 14.04.
The bug turns custom applications unusable.
Thanks!

[Test Case]
We found the memory leak while running the QGroundControl (QGC) application, so the steps to reproduce are the following:
1- Install QGroundControl dependencies.
sudo apt-get install git
sudo apt-get install qtcreator
sudo apt-get install qttools5-dev
sudo apt-get install qtbase5-dev
sudo apt-get install qt5-default
sudo apt-get install qtdeclarative5-dev
sudo apt-get install libqt5serialport5-dev
sudo apt-get install libqt5svg5-dev
sudo apt-get install libqt5webkit5-dev
sudo apt-get install libsdl1.2-dev
sudo apt-get install build-essential
sudo apt-get install libudev-dev
sudo apt-get install libsdl-dev
sudo apt-get install phonon-backend-gstreamer
sudo apt-get install libphonon4qt5-dev
sudo apt-get install flite-dev
2- Checkout of QGroundControl.
git clone https://github.com/mavlink/qgroundcontrol
3- Update QGroundControl Modules.
cd qgroundcontrol
git submodule init && git submodule update
4- Compile QGroundControl.
qmake ./qgroundcontrol.pro
make -j4
5- Run Application
cd release
./qgroundcontrol
6- Select "Radio / Serial Link" option on the window of connection selection.
7- While the application is run, execute htop to see the rising on the allocated memory of QGC, about 1MB / sec. |
