It's expected to be 499, not 500. If it's 500, it problably means
that there is some invalid error_page handling configured.

When talking to upstream servers, nginx tries to detect if a
client closed connection. If it does so, nginx terminates request
processing with the 499 status code. The
fastcgi_ignore_client_abort directive can be used to control the
behaviour in case of the fastcgi module, see
http://nginx.org/r/fastcgi_ignore_client_abort for details.
