    I have the new MBP 2012 and after upgrading to Mountain Lion the same thing happened on regular occasions. I have changed energy saving settings so it doesn't go to sleep.

    Next week I am due to re-image Mountain Lion when I get a new drive so I will see if the upgrade from Lion was the cause or not... or if Mountain Lion is the cause...
