Updated from 1.7.6 to 1.8.0, upstream_check module stop working. check_status page return error 500. nginx error_log says 2015/08/05 11:09:09 [error] 31278#0: *1 http upstream check module can not find any check server, make sure you've added the check servers, client: 192.168.2.xx, server: localhost, request: "GET /upstream_status HTTP/1.1", host: "192.168.2.xx" I found ebuild still uses check_1.7.2+.patch, so I downloaded check_1.7.5+.patch from project page to files dir, and changed epatch line. https://github.com/yaoweibin/nginx_upstream_check_module/blob/master/check_1.7.5%2B.patch Which patched with no problem and check_status page works again.

Works again in 1.9.3.
It should only affects version >=1.7.5 and <=1.8.0 . These versions should be patched with check_1.7.5+.patch, not check_1.7.2+.patch . Version >1.9.2 patched with check-1.9.2.patch, so it's fine.
This is fixed (I rebaked patch upstream).
