我正在尝试为我们的akka​​ http应用程序使用客户端连接池。但是，一旦达到最大连接数，请求似乎就会挂起。我将问题归结为以下几点：

import java.lang.Thread.UncaughtExceptionHandler
import java.net.ServerSocket
import akka.actor.ActorSystem
import akka.http.scaladsl.settings.ConnectionPoolSettings
import akka.http.scaladsl.Http
import akka.http.scaladsl.model.{HttpRequest, HttpResponse, Uri}
import akka.stream.ActorMaterializer
import akka.stream.scaladsl.{Flow, Keep, Sink, Source}
import akka.http.scaladsl.client.RequestBuilding._

import scala.annotation.tailrec
import scala.util.{Success, Try}

object AkkaProblem extends App {
    val server = new ServerSocket(0)
    val serverPort = server.getLocalPort

    object responder extends Runnable with UncaughtExceptionHandler {
       val cr = '\r'
       val httpResponse =
  s"""HTTP/1.1 404 Not Found$cr
