Perhaps it is working. Maybe 999,997 of those connections received HTTP 
503 errors. AFAIK, the returning of an error page doesn't break the 
TCP/IP connection. You could configure Apache to immediately close 
connections after the first request, but that might negatively affect 
performance for people who are not going above the connection limit.
