<div> </div>
<div>I run python in backend, and use nginx to proxy queries to python by using
fastcgi. I found some strange things in my nginx log those days. Some queries'
$request_time are up to 40 seconds which their $upstream_response_time are less
than 1 second.</div><div><br></div>
<div> </div>
<div>Here is my fastcgi related conf.</div>
