On reload nginx doesn't reopen listen sockets as long as they 
haven't changed in config, so it will never know your ips are no 
longer valid.

If something actually goes wrong during reload - nginx will log 
appropriate information to global error before giving up.  Note 
that it's already running master process which does a reload and 
there is no way to log to console ("nginx -s reload" merely sends 
SIGHUP to running nginx master process and was introduced mainly 
for Windows where one can't do "kill -HUP").
