Resolution
SYMPTOMS:Check PHP version and list of enabled modules from root shell, normally these commands should show an output:
# php -v
# php -m
In case of a problem no output is generated or segmentation fault happens.
CAUSE:
PHP IonCube loader extension is included several times or not in proper order.
RESOLUTION:
Find all IonCube loader entries in PHP configuration .ini files with command:
# grep -iR ioncube /etc/php*
Make sure that:
1) only one IonCube loader is included,
2) it corresponds with your PHP version, you can comment out all IonCube entries and check PHP version with `php -v`.
3) it is included before all other Zend extensions.
