Hey everyone,

Is this supposed to result in a graceful shutdown? Similar to if I would've called `ApplicationEngine#stop`? Currently, I am seeing all open requests result in `CancellationException`.

&gt; 2022-06-02 20:52:27.779 [eventLoopGroupProxy-4-3] DEBUG ktor.application - 500 Internal Server Error: GET - /health. Exception class kotlinx.coroutines.JobCancellationException: LazyStandaloneCoroutine was cancelled

This seems to be invoked to trigger the graceful shutdown.

<https://github.com/ktorio/ktor/blob/main/ktor-server/ktor-server-host-common/jvmAndNix/src/io/ktor/server/engine/EngineContextCancellationHelper.kt#L15|https://github.com/ktorio/ktor/blob/main/ktor-server/ktor-server-host-common/jvmAn[…]ix/src/io/ktor/server/engine/EngineContextCancellationHelper.kt>

But the cancellation of `enviroment.parentCoroutineContext` seems to cancel the `userContext` in `NettyApplicationEngine`.

Hey <@U4CP1J0QP>,

Sorry for tagging you but I was wondering if I should create a ticket for this on YouTrack? It seems like strange default behavior to me since I cannot imagine many scenarios where it'd be desirable to send the user a cancellation error rather than gracefully shutting down. WDYT?

Yep, could you log an issue? We will take a look :)
