How to go about tracking down this error?

I'll produce another log for you (attached), or you can try it for yourself: if you drop the baudrate in the test down to 9600, you'll see you get more recv events before all the serial data has been buffered by ipdHandler and the deltatime between each one is ~500ms. Once the idpHandler is finished then the deltatime between each recv event is down to ~14ms
