有人可以建议导致此异常的原因以及如何调试它吗?
Can someone suggest what is causing this Exception and how to debug it?
推荐答案
这是由于:
- 最常见的是，在另一端已经关闭连接时写入连接；
- 通常情况下，对等方关闭连接而不读取其端已经挂起的所有数据.
因此，在这两种情况下，您的应用程序协议定义或实施都很糟糕.
So in both cases you have a poorly defined or implemented application protocol.
还有第三个原因，我不会在这里记录，但它涉及对等方采取故意的行动来重置而不是正确关闭连接.
There is a third reason which I will not document here but which involves the peer taking deliberate action to reset rather than properly close the connection.
