I have about a dozen Arduino Pro boards that I've bought from Sparkfun over the past 8 months, usually in orders of 3 or 4 at a time. In the past few weeks, 4 of the boards have started getting flaky. I have them mated with Adafruit datalogger boards, and they've been working great for months but recently they've stopped recording data after being deployed anywhere from a few hours to a few days after I put new batteries in and everything. When I go to retrieve the memory card, batteries are still good, the data card is empty or it stopped recording data shortly after being deployed, and the pin 13 LED on the Pro board is blinking rapidly. Pressing the reset button only makes the LED stop blinking if I hold down the reset button. When I let up, it goes back to blinking rapidly. Cycling the power off and back on seems to make it stable again, but it'll start blinking again a few hours later or the next day. Did I get a bad batch of Pro boards, or is there something else that is indicated by the blinking pin 13 LED?
