[Interest] QTimer Freeze in 4.8

[Cjb_SW Freescale]

Dear all,
I have a strange problem on one application.
It seems that all the QTimer that I use to refresh the GUI (both c++ and
QML) are blocked after some time of inactivity.
They resume to work immediately when I press the touchscreen (everywhere on
the display).
Then after some time (1hour typical) everything get freezed again until new
touch event occur.

I really don't know where to look, I'm using Qt 4.8.5 with QWS server on
embedded platform based on freescale iMX28.

Do you have any suggestion?
Thanks a lot
Simone
