Scaling down lots of big textures, too much complex stuff in the map, leaks, a big skybox surrounding everything instead of doing it properly, these could all cause that error iirc.

AllocBlock is responsible for lightmaps. If this error occurs then there are too many lightmaps being generated. The reasons stated above can cause that.
