Turn off "reflective caustics"

Also check that your glass material has affect shadows ticked. These blobs sometimes appear when that isn't enable on refractive materials.

I've had this happen when bringing in geometry from Revit -> 3ds Max....something gets screwy in the FBX export, or import.

 

If the above suggestions don't work, try the old fashioned override-material-on-certain-objects trick, to isolate the problem piece of the model. Consider remodeling that piece in 3ds Max.
