`nest start` doesn't wait for asynchronous shutdown hooks

[MrBartusek]

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

Running nest start and then terminating the application using CTRL+C doesn't await asynchronous shutdown hooks (onModuleDestroy, beforeApplicationShutdown, onApplicationShutdown). Instead, the process exits before they are completed, but the application still completes gracefully.

Things I've tried:

1. app.enableShutdownHooks(); is enabled
2. I've found a similar issue getting EADDRINUSE error when using start with watch mode with an async beforeApplicationShutdown #1614 that was fixed by --no-shell; however, it doesn't resolve the problem here.

Minimum reproduction code

https://github.com/MrBartusek/shutdown-bug

Steps to reproduce

1. Clone and setup my repo https://github.com/MrBartusek/shutdown-bug. Only changes are in app.module.ts https://github.com/MrBartusek/shutdown-bug/blob/master/src/app.module.ts
2. Run nest start
3. Terminate using CTRL+C
4. See error

Expected behavior

Running node dist/main waits for shutdown correctly, I would expect it would work the same here

I'm also seeing this, specifically I'm unable to stop an s6 overlay service.

@maruthang Since this fix, watch mode can no longer be stopped with a simple CTRL + C (I have to do it twice).
I’m running in cluster mode, and I didn’t have this issue before.

Thanks for reporting this @johaven! I'll look into the watch mode + cluster mode interaction and open a follow-up fix. The signal forwarding change should respect the watch mode context — will have a PR up shortly.

@kamilmysliwiec @maruthang the introduced fix stopped working recently, probably due to recent reverts in 11.0.20 or 11.0.21, could you please clarify if we need to open new issue or this one can be reopened?
