Hi We are using `compile io ktor ktor client apache 1 2 3 `

Question

Hi We are using `compile io ktor ktor client apache 1 2 3 ` in a full fledged ktor project we have We ve been quite happy with it but lately it seems some services detoriate over time and we start to see `IO Connection reset by peer` Now my first approach was to check the server that is receiving the calls we are making if they were being ddosed by us potential downtime etc but it seems that the http call doesn t even leave us Given the detoriation over time my mind goes towards stale connection or something of that sort Has anybody else experienced this kind of issue

We are investigating a similar issue Despite defining socket timeouts all our coroutines get stuck here ```Coroutine DeferredCoroutine Active 7ea38da2 state SUSPENDED at kotlinx coroutines CompletableDeferredImpl await CompletableDeferred kt 87 at io ktor client engine apache ApacheHttpRequestKt sendRequest ApacheHttpRequest kt 35 at io ktor client engine apache ApacheEngine execute ApacheEngine kt 37 at io ktor client engine HttpClientEngine$executeWithinCallContext$2 invokeSuspend HttpClientEngine kt 86 ```

I will create an issue for this with the ktor project please try <https kotlin github io kotlinx coroutines kotlinx coroutines debug kotlinx coroutines debug debug probes > and get a coroutine dump We also see requests stop leaving our hosts at some point and all coroutines are in state SUSPENDED

We will open an issue tomorrow with coroutine dumps Like I said above this is despite setting socket connect and connection lease timeouts that we have coroutines stuck indefinitely in SUSPENDED state
