The error is that you're running out of memory.
There are a few options you can do to fix this: - Have you tried lowering the lightmap resolution of meshes? - Have you tried adding a Lightmass importance volume around your playable area? (this is not intended to cover significantly large areas) - Have you tried reducing the number of meshes in your scene that need to have lighting built?
These are some thing that can help, but at lot of this depends on your system specs as well. Light building is a very intensive process and can use a lot of RAM depending on the things mentioned above. Alternatively you can try increasing the amount of RAM in your system. If you already have a lot (24, 32, or more GB of RAM), it's possible that static lighting is not something that would work best for this large of a scene.
