My advice is use proper tools to do so, for example SystemD, Container.
And you should never recover the unhandledRejection inside node.js.

Thanks for the suggestion!
Yeah, I have an idea that it's more related to Node.js exception handling. It seems like the issue could be resolved if I handle exceptions on every promise individually. However, I'm curious if there's a way to handle them more gracefully on a process or global level.

You can listen to the event and gracefully shutdown your application.

process.on('unhandledRejection', (reason, promise) => {
  // logging or something else...
});


process.on('uncaughtException', (err, origin) => {
  // logging or something else...
});

Remember DO NOT restart your application after you face those error, you may face unexpected condition.

close-with-grace is pretty handy for this.

Closing as this is not Fastify related.
