My guess is that a bug of some kind has crept into a driver or daemon, though I don't know what. I did notice during this last hang, that it occurred right as Cron was waking up, and XLoad showed a sudden spike in activity (I also heard the hard drive right as it died). And I did notice a problem with Cron sometime in the past. One of root's crontabs had somehow gotten messed up, and when I tried to edit it, it would never save the new tab, and Cron suddenly started running at 80% of my CPU. This particular problem has only happened the one time. Has anyone else noticed strange problems with Cron? And could that be the cause of these crashes if there is a bug in the program?
