title: Core dump file is not generated
body: <p>Every time, my application crash a core dump file is not generated. I remember that few days ago, on another server it <strong>was</strong> generated. I'm running the app using screen in bash like this:</p>
  
  <pre><code>#!/bin/bash
  ulimit -c unlimited
  while true; do ./server; done
  </code></pre>
  
  <p>As you can see I'm using <code>ulimit -c unlimited</code> which is important if I want to generate a core dump, but it still doesn't generate it, when I got an segmentation fault.
  How can I make it work?</p>
