I've seen something similar myself, but only when the sender sends the data more frequently than FlightGear is allowed to handle with the refresh parameter (60Hz in your example). > My question is, does FG have any kind of buffer itself?

It sounds to me a mismatch in sender and receiver frequency. Maybe you should throttle the sender to only send data packets at 60Hz also?
