Re: PostgreSQL database and other daemons crashing

[Spencer Anderson <spencer@xxxxxxxxxxxx>]

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..

that'd be my guess.  postfix *never* dies.  something external is
killing your processes.
