Comment (by sa2ajj):

 Interestingly, djmitche and I started to see a similar problem and in the
 corresponding `error_log` there's a plenty of line like this:

 {{{
 2014/12/07 17:32:19 [crit] 32474#0: *34786 mkdir()
 "/var/tmp/nginx/proxy_temp/5" failed (2: No such file or directory) while
 reading upstream, client: 188.238.241.82, server: nine.buildbot.net,
 request: "GET /scripts.js HTTP/1.1", upstream:
 "http://192.168.80.244:8010/scripts.js", host: "nine.buildbot.net",
 referrer: "http://nine.buildbot.net/"
 }}}

 After restarting nginx, things seem to be normal.

 So it needs to be watched to see if the problem re-occurs...
