Strange Shadow Boxes or X's Appear on the Terrain When I Add Lights

Hello all! I have a real quick question today. What is up with those boxes or X's of shadows on the ground when you add lights? What is causing this and how do you recommend I disable or get around (in other words: Fix.) it from happening? Thanks! Here is a picture showing a real quick example:

It's very strange...

you can take of hard shadows from the “shadow type option” and check your values for the light…make a new directional light…if that doesnt work reduce the size of your textures:)
