Cron: Out of memory, what to do, where to dig?

Question

PHP

Parse XML (simplexml), upload 1s, file 3MB. The script works fine on the site. I run cron - says little memory. I read that cron requires more memory.
What to do?
Warning: simplexml_load_file(): asdasd.xml:11425: parser error : out of memory error in ....

Answer 1

The server runs under its own php.ini, cron runs php in cli mode, in this mode another php.ini is used.
Increase the memory for the script somewhere around: /etc/php5/cli/php.ini

Answer 2

Add memory or increase swap (if any) or create.

Answer 3

You can increase the memory by adding a line at the beginning of the php script :
where the value "1000M" is the amount of memory you need
. This usually helps.
