A little swap is just like a cheap insurance policy. You hope you don't need it, but if you do, you are glad it was there. Even though the recommended swap is 2 times system memory, I have never made a swap partition over 2 GB. Maybe I am also flirting with disaster, but haven't been bit yet in years. Usually a run away process that hits into swap gives enough time for the kernel to kill it off before the whole system dumps. -- MailScanner is like deodorant...
