Prevent script execution based on current system memory usage

You can configure the system memory usage threshold above which the device prevents the execution of Juniper Extension Toolkit (JET) scripts. You can configure the start startoptions mem-factor statement for individual JET scripts or all JET scripts. The device does not execute the script if the system's memory usage exceeds the configured value at the time the script is invoked. Configuring a system memory usage threshold ensures that a device only executes essential scripts when there are limited system resources, thus enabling the device to continue performing all critical network functions.
