As long scripts are not running within safe_mode they are free to change the memory_limit to whatever value they want.
Suhosin changes this fact and disallows setting the memory_limit to a value greater than the one the script started with,
when this option is left at 0. A value greater than 0 means that Suhosin will disallows scripts setting the memory_limit
to a value above this configured hard limit. This is for example usefull if you want to run the script normaly with a limit
of 16M but image processing scripts may raise it to 20M.
Edit /etc/php5/conf.d/suhosin.ini and add e.g. suhosin.memory_limit = 512M ...
