[gidrobaton]

Good day! I have same problem with nginx-1.0.5 (and nginx-1.0.0)

root at true:/tmp/nginx-1.0.5# ./configure
--add-module=/tmp/nginx_upstream_hash-0.3.1/
--add-module=/tmp/healthcheck_nginx_upstreams/ --with-debug

error_log logs/error_log debug_http;

    upstream backend {
        ip_hash;
        server 172.16.0.130:81;
        server 172.16.0.130:82;
        server 172.16.0.130:22;
#       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';
    }

Where 81 and 82 tcp-ports is a tomcat, who answer "HTTP/1.1 200 OK\r\n"
with some fields and close connection.
And 22 is a localhost ssh server, who simply close tcp socket without
answer if nginx send "GET /PingAction.do HTTP/1.0\r\n" 

As i see in ngx_http_healthcheck_module.c 
"state 100" is a NGX_HEALTH_OK ( // Good + final states)
"state 201" is a NGX_HEALTH_BAD_STATUS (// bad + final states)

But in my case all inversely - :81 and :82 are good - they answer
"HTTP/1.1 200 OK\r\n"
and 22 is bad - he close connection without answer
