2528	nginx reload with quic reuseport: quic packet rejected rc:-1	murilo.b.andrade@…		"I observed some client timeout issue in http3 requests when nginx is recycle the workers (`nginx -s reload`)
== Requirements to reproduce the issue

1. You need a worker in `shutting down` status;
   a. We need a big dumb file in the server;
   b. We will use a slowly `curl` request to ""stuck"" one worker;
2. A SIGHUP signal (`nginx -s reload`);
3. http3 client, see [#point1 (This is the http3 client that I used)];

== Debug log evidence
