default_down=false isn't working

[daveres]

I have setup several upstreams with checks. After that, I tried to make a change in the upstream conf file and I make a stress test, I receive errors (no upstreams available) and I could see in the status page that several upstreams go down until the next check. I have just added "default_down=false" to avoid this behaviour but I still have problems.

My config:

upstream ups-wwwlogitravelcombr-cars { least_conn; {{range service "ups-wwwlogitravelcombr-cars"}} server {{.Address}}:{{.Port}} max_fails=3 fail_timeout=5s; {{end}}#check_http_send "GET /carsshowcase/chechkapp/SignIn HTTP/1.1\r\nHost:www.example.com.br\r\n\r\n"; check interval=3000 rise=1 fall=3 timeout=10000 default_down=false type=http; check_http_expect_alive http_2xx http_3xx; }
