A modern programming language that makes developers happier.

kotlinlang

I am currently out of reach from computer.. I will let you know when I try

<@U3ZLHBTLG> I tried printing `data`. And it prints successfully.

<@U5MPVGMQD> Data prints, but first print call from launch suspend lambda doesn't? If so, then you probably have something else in your program that is blocking all the threads in `DefaultDispatcher`

I also tried using a different thread pool
```
        launch(jedisSubscribeThreadPoolContext) {
            println("************************** async")
            newPostWS[data.userId]?.send(Frame.Text(data.payload))
            println("*************************** complete")
        }

```

I solved it using a thread
```
    Thread() {
        jedisPool.resource.use {
            it.subscribe(listener, "global")
        }
    }.start()

```

Which kotlinx.coroutines version are you using exactly?

yes, a thread that never stops.
I could not find couroutine version. I suppose it uses kotlin version:
```
    ext.kotlin_version = '1.2.0'
    ext.ktor_version = '0.9.3'

```

So it's implicitly version 0.23.3. Can you set up a bug reproducer open source project?
