Resolution Note:
The memory usage of the Editor, CPU lightmapper plus other applications running on the system at the same time might exceed the physical memory of the machine with no fall back to tiled baking. This is unfortunate but by design. Reducing memory usage will be addressed as part of a larger refactor of the baking backend.
The template triggering auto baking is a separate issue (case 1381591) and should be set to non-auto GI baking mode.
