Question

我正在使用Netty 3.2.4并且我正在尝试调试我的应用程序以解决错误，但我意识到在我开始使用Netty运行我的应用程序之后，每2秒我就会得到一个打开/关闭连接（通道）来自“无处”。

我抛出一个新的Exception来获取堆栈跟踪以发现它来自何处，并且我看到一个“DeadLockProofWorker $ 1”类正在运行，根据以下堆栈跟踪。

它来自哪里？为什么？可以避免吗？

Answer 1

从这看：

at org.jboss.netty.channel.socket.nio.NioWorker.close(NioWorker.java:593)
at org.jboss.netty.channel.socket.nio.NioWorker.read(NioWorker.java:355)

远程对等方关闭了连接。您的远程对等方是否使用半封闭连接？ Netty不支持半封闭连接，因此如果远程对等端只关闭了连接的一半，则连接将被关闭。
