[support] Drupal 7 catastrophe

[Roger]

Drupal and/or PHP will not start, it's memory use grinds the whole 
computer system to a halt. It is not possible to switch themes or turn 
off modules. I believe that PHP does not read /etc/php.ini but there are 
no other files for it to read and phpinfo() reports /etc/php.ini
