title: kill pserve(Gunicorn) specific server from pyramid
body: <p>i use pyramid with pserve running Gunicorn like this:</p>
  
  <pre><code>pserve production.ini
  </code></pre>
  
  <p>production.ini</p>
  
  <pre><code>[server:main]
  use = egg:gunicorn#main
  host = 0.0.0.0
  port = 8080
  workers = 3
  worker_class = gevent
  daemon = true
  </code></pre>
  
  <p>and it returns the PID</p>
  
  <pre><code>Starting server in PID XXXXX.
  </code></pre>
  
  <p>but i can't kill it by running</p>
  
  <pre><code># kill XXXXX
  -bash: kill: (XXXXX) - No such process
  </code></pre>
  
  <p>or</p>
  
  <pre><code># pserver --stop-daemon XXXXX
  No PID File exists in pyramid.pid
  </code></pre>
  
  <p>till now, i've been using</p>
  
  <pre><code>pkill pserve
  </code></pre>
  
  <p>but now, i have multiple servers running, so it will kill all my servers.</p>
  
  <p>how can i kill a specific running server?</p>
