Akka.Remote - 解開後無法將消息發送給遠程演員

Question

我正在使用Akka.Remote在服務器端服務應用程序和多個桌面客戶端應用程序之間進行通信。客戶端向服務器發送請求消息（使用Akka.net）並等待服務器回覆響應消息。客戶端應用程序是暫時的，這意味着它們通常連接到服務器，保持連接一段時間，斷開連接並再次重新連接。

我遇到的問題是，有時當客戶端從服務器角色斷開（通過關閉其ActorSystem）然後重新連接回服務器時，它在一段時間內不會收到來自服務器的任何回覆。幾分鐘之後，通信工作沒有任何問題。我發現當服務器向客戶端發送了一個迴應，這個客戶端在請求期間斷開連接並且不再可達時就會發生這個問題。服務器無法傳遞響應消息，並以某種方式將客戶端端點標記爲無效。

在日誌中（在服務器端），當客戶端斷開連接時，我收到以下消息。

[DEBUG] 2016-01-21 13:04:58.6151 received AutoReceiveMessage <Terminated>: [akka.tcp://qb@client:8090/user/qb] - ExistenceConfirmed=True ServerActor

[DEBUG] 2016-01-21 13:04:58.6725 Stopped Akka.Remote.EndpointWriter 

然後當客戶端嘗試重新連接時，我得到：

[DEBUG] 2016-01-21 13:05:15.5883 ConnectResponse [akka.tcp://qb@client:8090/user/qb] ServerActor

我懷疑這種行爲是Akka.net的功能，但是，我需要實現我的系統，使客戶可以斷開連接，然後重新連接回服務器而無需等待。有什麼辦法可以禁用隔離機制或正常關閉服務器上的客戶端端點，以便客戶端端點不會被隔離？

[ INFO] 2016-01-21 13:04:58.6550 Quarantined address [akka.tcp://qb@client:8090] is still unreachable or has not been restarted. Keeping it quarantined. - 就是這麼說的。節點被隔離，需要重新啓動actor系統。

但是，恕我直言 - 只是升級到我們週一發佈的Akka.NET 1.0.6。我們讓遠程政策經理比歷史上的脆弱得多。
