I was going to say the same... 1.6-2.0mb is not that much at all, but
those apache processes taking 245mb each confuse me a bit. Isn't it so
that apache won't kill the child process as long as it keeps receiving
connections? I am not sure how apache handles its pool of child
processes so I could be wrong.
