I attached a scirpt for checking oom_score of all exisiting process. (oom_score is a value used for selecting "bad" processs.") please run if you have time. This is a result of my own desktop(on virtual machine.) In this environ (Total memory is 1.6GBytes), mmap(1G) program is running. %check_badness.pl | sort -n | tail -- 89924 3938 mixer_applet2 90210 3942 tomboy 94753 3936 clock-applet 101994 3919 pulseaudio 113525 4028 gnome-terminal 127340 1 init 128177 3871 nautilus 151003 11515 bash 256944 11653 mmap 425561 3829 gnome-session -- Sigh, gnome-session has twice value of mmap(1G).
