title: Gunicorn CPU usage increasing to a very high value
body: <p>We are using Gunicorn with Nginx. After every time we restart gunicorn, the CPU usage took by Gunicorn keeps on increasing gradually. This increases from 0.5% to around 85% in a matter of 3-4 days. On restarting gunicorn, it comes down to 0.5%.
  Please suggest what can cause this issue and how to go forward to debug and fix this.</p>
