You can configure the start start-options mem-factor statement for individual JET scripts or all JET scripts. The device doesn't execute the script if the system's memory usage exceeds the configured value at the time the script is invoked. This configuration ensures that a device executes only essential scripts when system resources are limited, thereby enabling the device to continue performing all critical network functions.
