The code for the function framework is actually public in the GoogleCloudPlatform/functions-framework-nodejs repository (although not advertised anywhere).

In particular you can see there the cases where killInstance is used, which is the one triggering exit code 16:

const killInstance = process.exit.bind(process, 16);

These cases are (at the time of writing):

• uncaughtException
• unhandledRejection
