[SOLVED] Some baked shadows appearing white

Im using unity 5.0.1 to perform light-mapping. Some shadows that are generated after baking appear pure white. Mainly, these seem to be from items placed closely to walls:

does anyone know if this is a setting or can be avoided?
Thanks.

Apparently is was due to the "indirect resolution" being set too low. I changed it from 0.001 to 0.1, now the shadows are black.
