Your map has a leak - an area where the space inside the map can "leak" out to the void beyond.
If you try compiling the map, and then go to "View > Load Pointfile" in Hammer, it will create a red wiggly line that will lead you through wherever the hole in your map is.

If the red wiggly line goes through solid geometry, it's because ONLY world brushes can seal your map from leaks - func_detail, displacements and props cannot.
This is why it's commonplace to have nodraw brushes under displacements.
