I am having problem with WSOD on my site. I have a lot of modules so my php execute time is 60s and allocated memory is 512MB. This error comes not regularly this is the biggest problem, and I cannot reproduce it.
The http request at that time is 200 what means its ok, my memory and processor usage is fine. But I have no error on php and apache2 level that means something dies even before it could log anything. If I try to debug it and put code in the index.php the problem dissapears and the site is visible, with the apache restart as well.
Other strange thing, I have a test copy of the site, on the same server. If I load the test site the problem dissappears like on apache restart.
- I went throught the Drupal WSOD document (https://drupal.org/node/158043) and tons of forum posts.
I have this in my settings.php, and index.php file as well.
error_reporting(E_ALL); $conf['error_level'] = 2; ini_set('display_errors', TRUE); ini_set('display_startup_errors', TRUE);
The error reporting is setted on php and server level as well. Still no sign of errors and solutions.
