title: nginx errors readv() and recv() failed
body: <p>I use nginx along with fastcgi. I see a lot of the following errors in the error logs</p>
  
  <blockquote>
    <p>readv() failed (104: Connection reset
    by peer) while reading upstream and
    recv() failed (104: Connection reset
    by peer) while reading response header
    from upstream</p>
  </blockquote>
  
  <p>I don't see any problem using the application. Are these errors serious or how to get rid of them.</p>
