No, it's impossible for you to be using sockets improperly -- unless you have
SOCK_RAW code in your application.
The bug is neither in Qt nor in your application. The bug is in the OS itself,
either in the sender by sending invalid packets or in the receiver by
erroneously discarding/misinterpreting them. It might also be in the hardware
or infrastructure, corrupting the packets.
But it can't be above the BSD socket layer.
