I tried <strong>keepalive_requests</strong> in my nginx config, but no luck. Finally, after going through the nginx source for instances of "1000", I found <a href="https://nginx.org/en/docs/http/ngx_http_v2_module.html#http2_max_requests">http2_max_requests</a>, which defaults to 1000. Increase that to an enormous number, restart nginx, everything works fine.</p>
