Drupal7 site fails to load (after enabling opcache on standard installation)

[MichaelMarkieta]

I wanted to see if the Zend opcache would work in my environment so I installed a standard drupal 7 site here: http://geoweb.geography.ryerson.ca/

Here is my opcache.ini

zend_extension=/usr/lib/php5/20090626/opcache.so
opcache.enable=1
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
opcache.revalidate_freq=60
opcache.fast_shutdown=1
opcache.enable_cli=1
opcache.error_log=/var/log/apache2/opcache.log

phpinfo() here: http://geoweb.geography.ryerson.ca/info.php

Wondering why enabling opcache breaks the standard drupal installation? Can someone see something obvious that I am missing (the site works with Zend opcache disabled)

Try it without Suhosin. We only test with stock PHP, although I don't really see why Suhosin would get in the way here.

Under @rlerdorf guidance, I set off to disable Suhosin

suhosin.simulation = On

Without any luck...

So I upgraded PHP:

sudo add-apt-repository ppa:ondrej/php5-oldstable
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

which brought me up to PHP 5.4. I also updated my zendopcache installation

sudo pecl uninstall zendopcache-7.0.2
sudo pecl install zendopcache-7.0.2

Updated my opcache.ini

zend_extension=/usr/lib/php5/20100525/opcache.so
opcache.enable=1
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
opcache.revalidate_freq=60
opcache.fast_shutdown=1
opcache.enable_cli=1
opcache.error_log=/tmp/opcache.log

and enabled it

sudo php5enmod opcache

and now it works!

Note... the other option would have been to rebuild PHP 5.3 without Suhosin but I am not reliant on that version.
