Question

在我们的应用程序中，我们具有路由JSON文档的路由。这是一个示例：

/** GET api/1/tenant/(tenantId)/ads/ */
def getAllAdsByOwner(advertiserId: AdvertiserId): Route =
  get {
    httpRequiredSession { username =>
      getAllTenantAds(username, advertiserId) { (adSource: Source[AdView, Any]) =>
        complete(adSource)
      }
    }
  }

大多数情况下，它可以按预期的方式工作，但是有时，尤其是在有多个同时请求的情况下，服务器会在发送标头后立即开始重置连接。我测试了一个脚本，该脚本在循环中使用curl请求此路由，如果请求失败，则中止。在停止之前，它已经运行了大约2分钟。请求失败时的跟踪如下：

在Wireshark中检查了相同的请求：

阅读日志并没有暗示问题的可能根源。响应记录为成功：

[27-06-2018 19:44:52.837][INFO] access: 'GET /api/1/tenant/ca764a91-8616-409c-8f08-c64a40d3fc07/ads' 200 596ms

使用的软件版本：

斯卡拉：2.11.11
akka：2.5.13
akka-http：10.1.3

配置：

我尝试将akka.http.host-connection-pool.max-connections增加到128，但这没有帮助。也许有人知道这是akka-http中的错误还是配置问题？

用流进行响应有时会导致“对等连接重置”错误
