502 Bad Gateway Send File failed (32: broken pipe)

[abdelrahm...@gmail.com]

I followed all the instructions found in the Production install documentation,
however when I try to do the basic collection test with curl I get a 502 Bad Gateway error.

When I check the nginx error log I get

2016/08/22 15:16:44 [error] 4874#0: *7 sendfile() failed (32: Broken pipe) while sending request to upstream, client: 194.171.252.103, server: crash-reports, request: "POST /submit HTTP/1.1", upstream: "uwsgi://unix:/var/run/uwsgi/socorro/socorro-collector.sock:", host: "crash-reports"

This is my nginx.conf file

Does anyone have any idea what I'm doing wrong?
