Using the system command with an ampersand at the end isn't running the process in the background
<p>I'm making a simple call to restore a mysql backup that takes about 45 minutes to complete on one of my servers.</p>

<pre><code>system("mysql -u$user -p$pass $db &lt; '$file' &amp;");
</code></pre>

<p>Running it that way locks my browser and I have to wait until it's finished before I can do anything.  This works fine on my other server.  What settings could be preventing that from working on the first server?</p>
