I've personally had only two Kernel Panics since upgrading to OSX several years ago (started at 10.1 and am now at 10.4.8). A co-worker of mine however gets one every three to four months. She has the identical system to me, Dual 1 Ghz G4 Quciksilver. Whenever they happen I usually just shrug it off, reboot and continue. At what point should we be concerned? Is one ever three to four months too often?
