Hi, All! I got an issue with leaking sockets in CLOSE_WAIT state. I have a ktor server connecting with mobile clients using websockets.
Websocket handling cycle is just copied from chat demo application for ktor:
private suspend fun DefaultWebSocketServerSession.handleWebSocketSession() {
val session = WebSocketSession(this, sessionService)
try {
for (frame in incoming) {
if (frame is Frame.Binary) session.handleFrame(frame, endpoints)
else if (frame is Frame.Text)
close(CloseReason(CloseReason.Codes.PROTOCOL_ERROR, "Text frames are not supported"))
}
} finally {
session.close()
}
}
My server is behind an AWS Application Load Balancer.
There are some descriptions of what to do with a growing number of CLOSE_WAIT sockets for netty, but I don't see how they can be applied to this cycle.
Did anybody hit this issue or know where to look?

Websockets options are:
pingPeriod = Duration.ofSeconds(60)
timeout = Duration.ofSeconds(15)
maxFrameSize = 1 * 1024 * 1024
masking = false

The issue can be reproduced inside docker container with traefik as a load balancer, but not on the windows...

Seems that the issue was fixed in 1.2.3
