Client having problem with rebill-cronjob (exits after 4/5 rebills)

A client of mine is having problems with his rebill-cronjob. The billing cronjob exits after (about) 30 seconds and most of the time 4 or 5 rebills.

This is the message sent by crond:

lynx: Can't access startfile
I have set max_execution_time to 300 (instead of 30 seconds) for all these php.ini's on my cPanel server and it's given correctly in phpinfo.php;
Code: 
/var/cpanel/version/php.ini-2
/etc/php.ini
/usr/lib/php.ini
/usr/local/lib/php.ini
/usr/local/lib/php.ini.new
/usr/local/cpanel/3rdparty/etc/php.ini

Questions
Would using /usr/bin/php instead of /usr/bin/lynx make any difference?
How can I let the lynx output be sent to my e-mail adress?
Is there any problem with lynx maybe? It automaticly exists after xxx seconds?
I am running APF Firewall, is that a problem?
Is Apache exiting running the php-file or is lynx exiting?

Any advise is welcome!
