title: APC (Alternate PHP Cache) Throwing Lots of PHP Notices
body: <p>I got APC 3.1.9 setup on my Linux box running PHP 5.3.6.</p>
  
  <p>Caching works fine but I have noticed in our error logs, that APC throws a lot of PHP notices, such as:</p>
  
  <blockquote>
    <p>[Wed Jun 29 01:08:56 2011] [error]
    [client ip] PHP Notice: 
    require_once() [function.require-once]:
    apc_cache_find [16085954]\n in
    /path/to/file on line 75, referer:
    /path/to/referer/file</p>
    
    <p>[Wed Jun 29 01:08:56 2011] [error]
    [client ip] PHP Notice: 
    require_once() [function.require-once]:

    /path/to/file on line 84, referer:
    /path/to/referer/file</p>
    
    <p>[Wed Jun 29 01:08:56 2011] [error]
    [client ip] PHP Notice:  Unknown:
    apc_cache_find [16215361]\n in Unknown
    on line 0, referer:
    /path/to/referer/file</p>
  </blockquote>
  
  <p>--> /path/to/file &amp; /path/to/referer/file have been inserted by me replacing the original file names</p>
  
  <p>Any idea why APC throws all these messages ?</p>
