Most likely you are see double errors with 404 being the last 
one.  By default nginx returns builtin error page in such cases, 
unless recursive_error_pages is set.  (And it's not really good 
idea to change the default unless you understand what are you 
doing and sure it won't create loops.)

I would recommend to

a) use static files for error pages;

b) make sure no limits are applied to error pages location.
