Core: out of memory

Hello.
I have following problem:
ibb . co / 6gNKrkZ (pease remove spaces then insert this into your browser and press enter to see the error report)

This occurs about once per day (~ 1-2 hour of play), sometimes after a few minutes into a coop game.
My machine and game ran fine since I can think, so something has caused this:
I played a more heavy game which crashed the Pc often and destroyed my HDD.

But what is the problem now? Starcraft 2 is well below my spec.
What does the error report mean? So that I can further investigate, I have not found this error report in the Blizzard support.

Thank you in advance.
