Without including the wads it is well under the size limit if that limit exists
But the server still crashes (maybe I shold mention that this is a dedicated server problem it works fine locally on your computer). Therefore we (my co-mapper and me) think the server is still reading the wad and bsp as one or something. It's a strange bug but from what we have seen it only occurs in really big maps. That's why we think that it got something to do with bsp size.
