Hi, I agree with Jörg. The polygon that is used in the query is about 19000 km wide. Run shp2img with for smaller bbox with -e switch https://mapserver.org/utilities/shp2img.html. However, there may be something to improve in the mapfile and layer maxscaledenom because it does not make sense to render buildings at that scale.

I guess the buildings of the whole USA need a lot of space (talking about your database and memory not the real world ;) ) I tink theres nothing wrong with your MapServer-Configuration, loks more like a message from PostGIS. Have you looked into the pg-log? you might check the memory-usage in taskmannager during the request. Have you tried the sql-query directly in pg (psql, pg-admin)? You also coud try to test a smaller bbox.
