We run everyday a PHP script that updates our database from a xml file on same server. Everyday I recessiv the following email on 9:00 AM.

Already updated max_execution_time =0, memory_limit=-1

Hello,

Could you provide some more information about this script? How large is the XML file? You may also find this third-party URL helpful:
