title: PHP: settings memory_limits > 1024M does not work
body: <p>For bad reasons I need to set <em>memory_limits</em> higher than 1 GB for a directory, but on my PHP 5.2.17 on a <a href="https://en.wikipedia.org/wiki/Debian_version_history#Debian_5.0_(Lenny)" rel="nofollow noreferrer">Debian 5.0</a> (Lenny) server when I use, for example, 2048M, I get only the <em>php.ini</em> default value (256M).</p>
  <p>PHP runs as an Apache module, and <a href="https://www.php.net/manual/en/function.phpinfo.php" rel="nofollow noreferrer">phpinfo</a> gives us (for the directory):</p>
  <pre class="lang-none prettyprint-override"><code>memory_limit    1024M    256M
  suhosin.memory_limit    0    0
  </code></pre>
  <p>Is there a limitation due to an Apache module, or the PHP configuration? I know the server only has 4 GB of RAM. It's just a special script.</p>
