These are the tests. I'm using a network module (hardware device) here which 
I control via SNMP. I can't write a small program, because it'll not be so 
small and it'll not work without the device.

But I'm using the method through the QUdpSocket class.

I'm just saying it's possible this method to have a bug with randam 
occurance. I can't define what's the reason for it.

Patric
