I run Prestashop 1.6.0.9 on a Debian Wheezy dedicated server with Apache2 and PHP 5.4 with APC and 32Gb of memory on the server.

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. I allow 2Gb to shm_size (32Gb available on the server) and change the mmap_file_mask to /var/temp (folder created and permissions to root).

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!

APC is horribly buggy, which is one reason why it's no longer in PHP by default since 5.5. Use memcached instead. – Michael Hampton Dec 06 '14 at 07:33
I read it's not recommended to use memcached if I have only 1 server in my architecture. – Xavier Dec 06 '14 at 08:02
There's a lot of bad advice on the Internet :) – Michael Hampton Dec 06 '14 at 08:27
The advice will be to use memcached or use php 5.5 with OPCache Zend? – Xavier Dec 06 '14 at 09:22
