Uncommanded Restarts

I think this is happening to me too.

8-core Mac Pro (2008 model) OS X 10.6.8. I was able to reliably reproduce the restarts when I was trying to run an Office 2011 updater at the same time that Sophos was running its daily auto-update. As soon as I waited until Sophos had finished updating then I could update Office without the computer doing an unplanned restart. But the computer restarted itself yesterday too when I was not doing anything at all and I believe it happened during the Sophos autoupdate. Prior to this, I was getting lots of unplanned restarts, similar to PC it was happening about 2 or 3 times a day. Replaced a hard drive and the problems went away for a few weeks until yesterday. No warnings - the screen just suddenly goes black and then the machine starts up again.

I can not say for certain if yesterday's restart had anything to do with Sophos but I will be uninstalling Sophos and seeing if the restarts happen again.
