Could not produce class with ID 152

When I try to use Application.LoadLevel(SceneName) I get the error

WARNING -> applicationDidReceiveMemoryWarning()

The scene I am loading is rather large if that helps. Trying to do this on a iPad.

Any thoughts?

Found a work around. If you are in a large Scene, you cannot load a large Scene. Make a scene with one gameobject and attach a script that loads the big scene.
