Unfortunately I am not > familiar with debugging, but I can provide anything what you need. I am not familiar with the Humminboard board, though it looks like the UART is available via the GPIO pins. Getting a debugging setup running is not simple task, though it might help in future :) Another way to debug this is trying to reduce the problem. From your description the mpd itself could just have a severe memory leak and that is not handled correctly. As starting point you could try to get some mpd logs out before it freezes?
