title: Django lightweight development Web server can't run for a long time
body: <p><strong>Django 1.11</strong></p>
  
  <p>I decided to demonstrate what I have done to my friends. I have paid for hosting, installed nginx and proxied the requests to Django.</p>
  
  <p>Then I went to the project directory and typed "python manage.py runserver".</p>
  
  <p>Well, this is for demonstration purposes. It is not a production.</p>
  
  <p>The problem is: in about half an hour the process disappeared. And nginx shows 502 Bad Gateway. When I run in Linux "ps aux | grep runserver", there is no development Web server running. So, it disappeared.</p>
  
  <p>Why the process disappeares? Where can I find any settings to regulate the life time of this process?</p>
