That may in fact be the cause. I ran, free -lm -s 0.5, to watch my memory use and saw the output below. My processes didn't die this time when it hit zero bytes free, but it only lasted for 1 second. Some process must be occasionally using very excessive memory, and every once in a while, I get the OOM kill scenario. Guess I need to find that process..
