Ahhh, you have met the zombie process. A nice critter that hangs out sometimes not doing anything but taking up swap space sometimes using up tons of CPU cycles trying to get that interrupt that it shal never get. Oh well maybe it'll die by itself, but a reboot is sometimes the only way to rid the machine of these creatures of the dark.
