Re: PostgreSQL database and other daemons crashing

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..
