编辑：我已经更新了日志片段，以显示dispatcher线程数超出了我的预期。

编辑#2:以下是健康检查路由代码：

class HealthCheckRoutes()(implicit executionContext: ExecutionContext)
  extends LogHelper {

  val routes = pathPrefix("health-check") {
    pathEndOrSingleSlash {
      complete(OK -> "Ok")
    }
  }
}

Answer 1

可能吧，是的。我想这是线程名。

如果您在服务器上进行线程转储，那么它是否有很多打开的线程？

看起来您的服务器每个连接都泄漏一个线程。
