 ===== PHP Processes Won't Run Forever =====
-PHP Detached Mode doesn't mean that PHP will run forever. It will still follow the [[https://www.litespeedtech.com/docs/webserver/config/extapps/lsapi#extMaxIdleTime |Max Idle Time]] setting. If you want to make PHP live longer, just increase **Max Idle Time**.
+PHP Detached Mode doesn't mean that PHP will run forever. It will still follow the [[https://www.litespeedtech.com/docs/webserver/config/extapps/lsapi#extMaxIdleTime |Max Idle Time]] setting. If you want to make PHP live longer, just increase **Max Idle Time**.  Never set it to ''-1'' to indicate "unlimited" since, in process group mode, values under ''30'' will be automatically converted to the default of 30 seconds. If you want PHP to be running longer, try to enter a large number, such as ''3600''.
+===== Changes to detached mode will be effective when a request comes =====
+Detached mode app wont be started when server startup, only when there is traffic hitting the external app, it will be started on demand, and stay there if LSWS restarts.
+The same for the restart, only if an external application is about to serve a request, it will be checked if restart is needed.
 ===== PHP Auto Configuration for Different Control Panels =====
 In previous versions of LSWS (5.2.x and earlier), external apps and PHP handlers are set up via the **External App** and **Script Hander** sections, respectively.
