That would be due to OS, and hardware rather than C2.
You could try stopping some other resources that are also using ram, as its most likely the culprit.
I don't think so that my PC is the cause for it barely heats up even though it's a fanless ultrabook, I have enough ram in my pc. And it happened in two of my Computer.
Task Manager Overall Usage:
Ram Consumption : 10 to 20 %
CPU Consumption 3 to 25 %

But it is nothing serious actually cause it happens only when you use it for a very long time and frequently using redo, undo, copy, paste and heavy import of objects and heavy event making. But I still reported it for some people may get confused that their events doesn't work suddenly and object images (especially similar images or duplicated-edited images) interchanges.
