title: nginx + uwsgi: -- unavailable modifier requested: 0 --
body: <p>Ubuntu 12.04, nginx 1.2.0, uwsgi 1.0.3.</p>
  
  <p>I start uwsgi with the following command:</p>
  
  <pre><code>uwsgi -s 127.0.0.1:9010 -M -t 30 -A 4 -p 4 -d /var/log/uwsgi.log
  </code></pre>
  
  <p>On each request nginx replies with 502 and uwsgi writes to log the following line:</p>
  
  <pre><code>-- unavailable modifier requested: 0 --
  </code></pre>
