PHP APC cause a max exec time error after 2-3 hours

[Sniper Zone]

Hi,

 

I run Prestashop 1.6.0.9 on a Debian Wheezy dedicated server with Apache2 and PHP 5.4 with APC.

 

The shop perfectly run without using APC, but when I enable this little guy, after 2-3 hours, I have this problem:

FastCGI: server "/var/www/xxxxx/cgi-bin/php5-fcgi-*-80-xxxxx.eu" stderr: PHP message: PHP Fatal error:  Maximum execution time of 30 seconds exceeded in /var/www/xxxxx/classes/cache/CacheApc.php on line 50

and after an hour, this cause a code 500:

FastCGI: comm with server "/var/www/xxxxx/cgi-bin/php5-fcgi-*-80-xxxxx.eu" aborted: idle timeout (3000 sec)

On line 50 of this file:

	protected function _set($key, $value, $ttl = 0)
	{
		return apc_store($key, $value, $ttl);
	}

PHP APC configuration is based on this guide: http://gregrickaby.com/the-perfect-apc-configuration/

I just changed some things to to fit with my system and allow 2Gb to shm_size (32Gb available on the server).

 

I don't understand what's the problem with APC. It run perfectly for a couple of hours, then he cause this major problem every time!

 

Someone have an answer and a solution to this?

 

Thank you in advance!
