I have been getting this error as well. I hadn't posted it because it seemed like an isolated issue, and frankly it isn't too bothersome; I see no performance decreases.
Interestingly, I installed 6956 on my sister's laptop, and she suddenly started to get the errors as well, so I thought it may have something to do with our installation or software we both use.
We seemed to have started to recieve the error sometime around the last windows update, but I'm not totally sure.
Its a hindrance, but not major.
Still, I'd like to resolve it.
