I have been using OS X on my iBook for about 2 years now and today I saw\nsomething I never saw before. My system was feeling sluggish and so I\nwent into top to find out what was wrong. My kernel task process was\nusing around 75% of my cpu instead of the usual 5-10%. It would\nsometimes peak at rates over 100%, which I didn't think was possible. I\nstarted quiting apps to see if that would help and when I quit Camino\nthe odd kernel task behavior stopped.\n\nDoes anyone know what caused this?
