title: Configuration Issues with PECL and PHP-FPM
body: <p>I'm using Ubuntu Natty. I recently installed NGINX 1.0.6 and PHP 5.3.8 (with --enable-fpm) from source. Everything went ok and I tested it with an info.php page with <code>phpinfo()</code>.</p>
  
  <p>I then installed APC and Memcache using PECL i.e. <code>pecl install apc</code>, etc. That seemed to go ok as well.</p>
  
  <p>However, when I edit my php.ini file and add the extension_dir and extension modules for both APC and Memcache, I get the following when I restart PHP.</p>
  
  <pre><code>Starting php-fpm PHP Warning:  Module 'apc' already loaded in Unknown on line 0
  &lt;br /&gt;
  &lt;b&gt;Warning&lt;/b&gt;:  Module 'apc' already loaded in &lt;b&gt;Unknown&lt;/b&gt; on line &lt;b&gt;0&lt;/b&gt;&lt;br /&gt;
  PHP Warning:  Module 'memcache' already loaded in Unknown on line 0
  &lt;br /&gt;
  &lt;b&gt;Warning&lt;/b&gt;:  Module 'memcache' already loaded in &lt;b&gt;Unknown&lt;/b&gt; on line &lt;b&gt;0&lt;/b&gt;&lt;br /&gt;
   done
  </code></pre>
  
  <p>When I open the info.php file to check what loaded, everything seems ok i.e. I see APC and Memcache references in the information.</p>
  
  <p>But when I uncomment the extensions i.e. <code>;extension=apc.so</code> and <code>;extension=memcache.so</code>, there are no errors, but the APC and Memcache listings in PHPinfo no longer appear.</p>
  
  <p>I'm not sure how these extensions are being loaded twice and from where. I'd appreciate some guidance.</p>
  
  <p>Thanks in advance.</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>I'm using PHP-FPM and using <code>lsof -i -P</code> it appears that I have multiple pools of PHP-FPM running. Could this be part of the problem why I am seeing this error?! Is there a way to fix this?!</p>
