kotlinlang

Hi there. Recently i built a load-testing tool for our websocket service based on ktor http client (CIO). But for some reason i only can reliably run load against local instance of service. When i'm pointing tool at remote (staging) instance program start to crash with `java.lang.StackOverflowError` with some enormous stacktraces involving coroutines resume and ktor.util.pipeline.SuspendFunctionGun.resumeRootWith. The only difference between local and remote instances is enabled tls on remote and latency. Snippet:
```        at kotlin.coroutines.jvm.internal.BaseContinuationImpl.resumeWith(ContinuationImpl.kt:46)
        at io.ktor.util.pipeline.SuspendFunctionGun.resumeRootWith(PipelineContext.kt:219)
        at io.ktor.util.pipeline.SuspendFunctionGun.access$resumeRootWith(PipelineContext.kt:67)
        at io.ktor.util.pipeline.SuspendFunctionGun$continuation$1.resumeWith(PipelineContext.kt:118)
        at kotlin.coroutines.jvm.internal.BaseContinuationImpl.resumeWith(ContinuationImpl.kt:46)```
Full traceback of one fail: <https://pastebin.com/dVi5R5ty>
ktor 1.3.1, kotlin 1.4.10, kotlinx.coroutines 1.3.9
How do i fix or debug this?
