When I turn off apc.stat it causes a 500 internal server error. I checked the apache error_log and it's something about:

[Tue Jun 26 10:02:59 2012] [error] [client] PHP Warning:  require(): Filename cannot be empty in /var/www/site1/public/index.php on line 17
[Tue Jun 26 10:02:59 2012] [error] [client] PHP Fatal error:  require(): Failed opening required '' (include_path='.:/usr/share/pear:/usr/share/php') in /var/www/site1/public/index.php on line 17

I checked that line and here's what it contains:


I don't see anything wrong with it. Here's my current APC config:

APC version: 3.1.10 PHP Version: 5.4.4

How do I resolve this error when i disable apc.stat?


I regret I'm gonna have to answer my own question after a few times of google search and bites of doughnut.


It's a bug when using relative includes and apc.stat=0
