Unhappy Vray Render - White bleeding in shadows

Hi guys,
I have a problem with my render, can't get it right. Some white shadows shows where is supposed to be real shadow, almost like a reflection. I tried different settings for vray very high and low, nothing changes.

Thank you!

I believe these are called "light leaks". If I'm not mistaken you should make sure the corners of the room are absolutely sealed, preferably the walls should intersect so you're sure, and having them being made by boxes (so they have thickness) also does the trick I think.. Look below for intersection:
