title: How to avoid duplicating workers with Symfony local server?
body: <p>I found out that I have quite many Symfony local web server workers registered (around ~35), and the number keeps growing. I usually just start server with <code>symfony serve</code> and then kill it (Ctrl + \) when no longer needed. Apparently killing it leaves a worker behind, as seen in <code>symfony server:status</code>. Running <code>symfony serve</code> again just creates a new worker.</p>
  <p><code>symfony server:status</code> output:</p>
  <pre><code>Local Web Server

  <p><strong>So my questions regarding this:</strong><br />
  <strong>#1:</strong> is it possible to quickly kill the server? I assume <code>symfony server:stop</code> is more correct way, but that requires additional console window and entering the command.<br />
  <strong>#2:</strong> how to kill those workers that are registered from previous sessions? Trying e.g. <code>kill 6327</code> says that there's no such process. Also they're not gone after system restart.</p>
  <p>Those extra workers are bothering me because for each one of them the server log output in the console is duplicated. So right now on each request to the server I get around 3k lines of log output in the console. Which makes it pretty useless.</p>
