I'm trying to mesh an object that consists of a solid cube with a group of spheres subtracted from the solid cube. Upon meshing anything, I get the following errors:

"Error: Face.118 has less than three boundary nodes on one or more of the face node loops, which prevents it from being meshed."

I receive this on numerous faces of the object. I also get an error related to skewness such as:

"mesh of face face.37 contains highly skewed elements (EQUISIZE SKEW > 0.97)"

I was thinking that there might be problem with the curved surface of the spheres being so close to the flat surface of the wall....but again I have no clue. Any thoughts?

I believe the problem was a singularity in the geometry... which created a problem in meshing. The only way I could think of correcting this is to alter the geometry so that there was a small (0.01*sphere_diameter) space between the spherical objects. I have a mesh created, but again it is not ideal. Anyone else have any better thoughts to get around meshing singularities?
