High PHP-FPM CPU usage bringing site down - Drupal Nginx PHP5
I am running drupal with Nginx on ubuntu 14.04, 4gb memory DO plan. and PHP5 and on htop i notice that the CPU usage is 100%,
In htop the top processes are
www-data (virt 56680, res 4540, command php-fpm: pool drupal)
There are a number of the above pool drupal php-fpm processes taking up lots of CPU.
I have enabled opcache in php.ini (not cli)
Does anyone know how I can get the CPU down? Its strange as it started happening for no apparent reason.
