This is a kown issue and will be solved soon.

It can, but does not allways,  happen when 2 SSS surfaces are too close together.

Secondly; I see MSR at 0.1.
Did you set 0.1 in all the objects parameters palette also?
PP2012 manual page 396 if my memory is not fading :-)

Third: For best quality set Post filter size at 2 or 3 and Post filter type to sync.

Question?
Any special reason why Gamma Correction is OFF?

Happy Posering.
