499 is logged by nginx if client closes connection before nginx
was able to send anything to client.

Large number of 499 may indicate that something is wrong on your
server, e.g. response generation takes too long. Some number is
usually ok: you are expected to have some users closing
connections prematurely due to their internal reasons (e.g. bad
connectivity, closing browser while loading page and so on).

In nginx, 499 means “client has closed connection”. However, guys know
little about 499 as it’s not defined by rfc2616 but by nginx.

When a client sent a request, and closed the connection without waiting
for
the response, a 499 code occurs. If there’re a lot of 499s in your
access_log, it’s mostly caused by the slow back-ends (too slow for your
users to wait). You may have to optimize your website performance.
