Funny... even with suspendApp ( with the resource library for Ktor) and I still get things like what I posted in the thread...

Shouldn't suspendApp be shutting things down gracefully?

There is no such thing as magic 😅 You still need to properly use Resource and compose things.

Not that ctrl+c is not properly handled by Gradle, and it forcefully terminates the application SIGKILL. Hard to say what is going on without any code.
