I have a problem running a cronjob, i get an error when i check in my syslog as below: /USR/SBIN/CRON: (web30) CMD (/opt/phpfcgi-5.4.12/bin/php /var/www/clients/client11/web30/web/clients/artisan ninja:send-invoices #domain.name) /USR/SBIN/CRON: (CRON) error (grandchild #10584 failed with exit status 53) First of all i have 5.3 php version installed with my ispconfig server, but as the website is on laravel framework i had to initially install newer version of php. So 5.4 is additional version and it's selectable through the control panel. So far i didn't noticed any errors running the website on this version. Now i have setup a cron job in ispconfig control panel, but as users are not allowed to run cron jobs i have set up a cron job as an administrator, and the cronjob command is exactly as in logs above. I also see that command is executed as an user. When i look in cron.d i see ispc_chrooted_web30 file with following command. MAILTO='' SHELL='/usr/sbin/jk_chrootsh' * * * * * web30 /opt/phpfcgi-5.4.12/bin/php /var/www/clients/client11/web30/web/clients/artisan ninja:send-invoices #domain.name And when i try to execute command in terminal it works fine, i tried with both, root and web30 user, and command works fine and gets executed.
