Hi <@U017TSBJ2C9>, this bug also appears to exist with Netty.

<https://youtrack.jetbrains.com/issue/KTOR-7360|Link to the original ticket>

<https://github.com/ktorio/ktor/pull/4278|Link to your fix in CIO>

My team has since switched from CIO to Netty, and we've noticed that the code from the ticket stops almost immediately with CIO, but not with Netty

```fun main() {
  val server = embeddedServer(
    factory = CIO | Netty, // One of these
    environment = applicationEnvironment(),
    configure = {
      shutdownGracePeriod = 30_000
      connector {
        port = 8787
      }
    },
  ).start(wait = false)

  println("Stopping...")
  val time = measureTimeMillis {
    server.stop()
  }

  println("Stopped in $time")
}```
• With CIO, `Stopped in 7`
• With Netty, `Stopped in 60205`

Thank you. I've filed an <https://youtrack.jetbrains.com/issue/KTOR-8770|issue> to address this problem. This does not seem to be an expected behavior.
