PHP script is killed without explanation

Viewed 14575

I'm starting my php script in the following way:

bash  
cd 'path'   
php -f 'scriptname'.php

There is no output while the php script is running.

After a time, the php script responds with:

Killed 

My idea is that it reached the memory_limit: ini_set('memory_limit', '40960M');

Increasing the memory limit seemed to solve the problem, but it only increased the edge.

What exactly does that Killed phrase mean?
