Hi joneum,

Yesterday we upgraded to 1.18.0_15, and the module upstream_check stopped
working properly.

You can do a test using a simple config file:

<begin config file>
worker_processes 1;
worker_rlimit_nofile 262144;

load_module "/usr/local/libexec/nginx/ngx_http_upstream_check_module.so";

error_log /tmp/test/error.log debug;

events {
    worker_connections  16384;
    use kqueue;
    kqueue_changes 2048;
}


http {

        upstream cluster {

            # simple round-robin
            server 192.168.0.1:80;
            server 192.168.0.2:80;
            check interval=3D5000 rise=3D1 fall=3D3 timeout=3D4000;
        }

        server {
            listen 50080;

            location / {
                proxy_pass http://cluster;
            }

            location /status {
                check_status;

                access_log   off;
           }
        }

    }
<end config file>

<begin commands>
nginx -p /tmp/test -c test.conf
curl http://localhost:50080/status
<end commands>

And logs show:
