iMac restarts randomly?

[Jimmy Guphanti]

Ever since I updated to 10.8.2, my iMac will crash and reboot randomly. When I say randomly, I mean RANDOMLY. It happens about 6 times a day now. I turn it on in the morning and put it on sleep, and when I get home, I find that it crashed at some point during the day and restarted, and says that my computer was restarted because of a problem. I do not even have to be using it. It woke me up one night because it crashed at 1 am while on sleep and restarted. All the applications are quit. I contacted Apple, and they told me to try reinstalling the update, OSX, and restore from a backup. I did these things and it still crashes and restarts at random. This happens mainly while on sleep, or while trying to wake the computer from sleep. It is a Mid-2011 iMac. I appreciate any help.

Here is the crash log if it helps:

Have the same thing happen; much lower frequency though. Twice in the two weeks or so. Panic.

Right now I run memtest on my iMac 27" 2.9 2010 with 12GB; 4GB stock and 8GB added myself two years ago. Until recently I had no complain. Once the box is back from single mode I will look when I installed the last OS Upgrade; I'm on 10.8.2; might be linked.

Update: run one pass; took a bit more then an hour and boiled the system quite good. No issue found. But I understand that I should run the system a bit (means hours) longer. Will do with a bit more cooling in place.

The OS X 10.8.2 Supplemental Update got installed on October 5th; not sure if linked ...

Hi, I have the same problem from the 10.8.2 update, imac resets randomly, especially when to put it on sleep
I have an iMac Late 2009
