I'm currently receiving a fairly large HTTP flood right now, and it's causing my nginx reverse proxy to produce a 502 Bad Gateway.
I have a frontend server running nginx as a proxy to my backend server, but it's just getting a bunch of
connect() failed (110: Connection timed out) while connecting to upstream errors. Tons of them. If I bypass the proxy server to connect to the backend, I can run the site just fine, so I know it's in the reverse proxy somewhere. However, I have no idea how to determine why it's timing out.
running nginx 1.2.3 on CentOS 6.2
