我不知道它是netty 3.2.7.Final bug。问题是在客户端（使用SecureChatClient）意外地增加了recv-q中从服务器端（使用SecureChatServer）接收实时消息的数据包。 我想在应用程序级别读取数据包时会出现死锁。
这是netty 3.2.7的错误吗？或者你对recv-q的增加有什么看法？ 我在下面附加了netstat结果和jstack线程转储。

感谢Trustin的回复。这不是网络错误，也不是构建我们的服务。 Jstack线程转储也不正确。很抱歉。
一旦收到来自服务器端的消息，客户端就会将结果发送给第三方系统（HTTP）。由于默认超时设置，消息传递服务会挂起。
