spontaneous restarts

Earlier tonight my Mini restarted itself, unprompted, for the second time in the last 2-3 weeks. In both cases, I had been away from the machine for at least 5 minutes or more, then glanced over to see the grey boot screen w/ the apple logo and watched the machine reboot to the login prompt.

This time, I thought to go into Console and look at the system log; here's a brief snip leading up to the restart. Maybe someone can help.

Possibly/probably also worth noting:
- I don't have the machine set to require a password on resume from screensaver.
- In both cases I was probably was gone long enough for the screensaver to have started up (3 min).
- My screensaver is an iPhoto library, and my iPhoto library is on the external volume /media/. For several months I kept it on a different drive with the same volume name, then upgraded the drive, (copying everything over with SuperDuper) and named the new one /media/ as well, about a month or two ago. I strongly suspect that this has something to do with the restarts because of the fseventsd entries, and because it's the last entry before a long break and then the long break and the two one-second-apart entries from SecurityAgent and loginwindow

(While I'm asking, I guess I'll note that I'm really confused at seeing outoftheblue.local in there on the "kCGErrorFailure" line... I don't remember ever using that name for anything except one random virtual hostname in my Apache config that I use for local web development, and it's just one in a list of a bunch of others... yet that hostname appears in the logs below, and it also appears in system preferences as the access name for VNC, file and web sharing, even though the computer name specified just above is something else entirely (MisterMini) and the line right below it says that "Computers on your local network can access your computer at: MisterMini.local" --I have noticed that this has all been the case for a long time, though, so I doubt it's related to these two sudden restarts. Just been puzzled by that for a while.)

I am experiencing a similar problem.

The catalyst seems to be when I am using Video related applications, usually iMovie. The screen-saver activates after 15 minutes (standard tropical paradise system screen-saver) and when I go to wake the machine up, the screen goes blue and it goes to log-in screen.

I am using 10.6.6 on a Macbook Pro 2.2 Ghz Intel Core 2 Duo, 4 GB 667 Mhz DDR2 SDRAM, probably released mid-late 2007.

I have tried re-installing 10.6 (Snow-Leopard), but to no avail. Will try a complete re-build aswell (from 10.5, then 10.6), but any suggestions in the mean-time would be appreciated. I thought it could be motherboard, or video card, but it has been about 2 months now without getting noticeable worse.

Any hardware experts out there?
