nginx-1.0.5 was compiled with both patches:

root@true:/tmp/nginx-1.0.5# patch -p0 < ../nginx_upstream_hash-0.3.1/nginx.patch
patching file src/http/ngx_http_upstream.h
Hunk #1 succeeded at 106 (offset 1 line).

root@true:/tmp/nginx-1.0.5# patch -p1 < ../healthcheck_nginx_upstreams/nginx.patch
patching file src/http/ngx_http_upstream.c
patching file src/http/ngx_http_upstream.h
Hunk #1 succeeded at 110 with fuzz 2 (offset 4 lines).
patching file src/http/ngx_http_upstream_round_robin.c
patching file src/http/ngx_http_upstream_round_robin.h

root@true:/tmp/nginx-1.0.5# ./configure --add-module=/tmp/nginx_upstream_hash-0.3.1/ --add-module=/tmp/healthcheck_nginx_upstreams/ --with-debug
root@true:/tmp/nginx-1.0.5# make -j5 && make install

But if I use "hash" options, error.log is empty after nginx reload, even if I use "server" option, which indicates to closed port.

error_log /usr/local/nginx/logs/error.log;
upstream backend {
#ip_hash;
server 172.16.0.130:181;
server 172.16.0.130:182;
server 172.16.0.130:122;
hash $remote_addr;
hash_again 0;
healthcheck_enabled;
healthcheck_delay 5000;
healthcheck_timeout 1500;
healthcheck_failcount 1;
healthcheck_send "GET /PingAction.do HTTP/1.0" 'Host: ivis0';
}
