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.

2022-06-02 205227.779 [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/jvmAn[…]ix/src/io/ktor/server/engine/EngineContextCancellationHelper.kt

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

Hey @e5l,

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 :)
