On configuration reloading nginx starts new worker processes with
new configuration and old worker processes are terminated as soon
as they finish processing of requests. All keepalive connections
in old workers are closed accordingly. HTTP/1.1 clients are
required to handle keepalive connection close, so this shoudln't
be a problem.

It's not clear why you see RST instead of normal close with
FIN/FIN+ACK/ACK (are you?), but this shouldn't the problem by
itself anyway.
