在內核recv-q中增加客戶端數據包（用netstat確認）而不是讀取數據包

我不知道它是netty 3.2.7.Final錯誤。問題是，在客戶端（使用SecureChatClient）出乎意料地，在recv-q中增加了接收來自服務器端（使用SecureChatServer）的實時消息的數據包。我猜在應用程序級讀取數據包時出現死鎖。在內核recv-q中增加客戶端數據包（用netstat確認）而不是讀取數據包
它是netty 3.2.7的錯誤嗎？或者你有任何關於recv-q增加的想法？我已經在下面附加了netstat結果和jstack線程轉儲。

你正在使用一個漂亮的老版本的Netty。如何升級最新的穩定版本並讓我們知道您的發現？ – trustin
我同意升級。但我想知道在升級之前從錯誤報告中瞭解到這個問題。它是間歇性的，我不能再現... – shnam
我們的過程首先發送消息給客戶端（1EA），並在服務器上傳遞消息（8EA與2守護進程）。
其次，每臺服務器向客戶端發送結果消息。
三，客戶端將消息傳遞給另一個Web服務器。 – shnam
感謝Trustin的回覆。這不是網絡錯誤，也不是構建我們的服務。另外Jstack線程轉儲不正確。很抱歉。
一旦收到來自服務器端的消息，客戶端將結果發送給第三方系統（HTTP）。由於默認的超時設置，消息傳遞服務掛起。
