title: memory_limit = 1024M, still, Cannot allocate memory: couldn't create child process: /opt/suphp/sbin/suphp
body: <p>I know that there is another question with a similar title/error, but i think this is a different problem.</p>
  
  <p>Context: </p>
  
  <ul>
  <li>Running wordpress 3.6.1, PHP 5.3.27, MySql 5.1.70, on a shared Linux host, 1gb Memory.</li>
  <li>.htaccess: <code>suPHP_ConfigPath /home/[username]/public_html</code></li>
  <li>php.ini: <code>memory_limit = 512M</code>  (I tried 2048M, 1024M, 32M, .. heck even -1)</li>
  <li>I also tried (<code>ini_set(/* all the values above, in the WordPress index.php */)</code>)</li>
  <li>I disabled ALL plugins, I even re-enabled one by one.</li>
  <li>I have about 300-400 concurrent connection/users on the site at the same time, on average.</li>
  <li>I DO NOT have SSH access :/ </li>
  <li>I cannot reproduce the bug locally (On Mac running '<code>MAMP</code>' and '<code>ab</code>', I even lower the mem limit locally to 16m.. )</li>
  <li>the way I know that none of that worked is that, in the /cpanel errorlog screen, I see the Error (in the title) about 3-4 times per minute !!! <code>(12)Cannot allocate memory: couldn't create child process: /opt/suphp/sbin/suphp for /home/infomed/public_html/index.php</code></li>
  <li>I already called the hosting company, directnic, and they weren't able to help me much, they suggested few of the solutions that I already tried, they don't support SSH, so that's a dead end for me. I know I can switch hosts, but I am not able to do so at the moment.</li>
  </ul>
  
  <p>Please, all I am asking is to point out any potential other causes that I can investigate, I am out of ideas ... what could use more than 1gb of memory, in a simple Wordpress blog, all plugins disabled, on the home screen? there is no images upload happening, just 2 <code>wp_get_recent_posts</code> each with a limit of 6. </p>
