If you are instrumenting an application running on MacOS X, you need to instrument it manually using the shell script

If you are installing the PHP Agent on MacOS X, set max_execution_time to 0 in the appdynamics_agent.ini file

If you have another INI file that is loaded after appdynamics_agent.ini, and sets max_execution time to a non-zero value, set max_execution_time to 0 in the php.ini file instead.
