错误是[Errno 131]由对等方重置连接后跟错误：[Errno 9]错误的文件描述符

Question

我正在使用python聊天室服务器from this code但是我在运行客户端的异常行为时出现问题，当我的Android客户端切换到另一个网络然后我的服务器挂起并停止工作切换回聊天服务器网络。 首先我得到错误

error is [Errno 131] Connection reset by peer 

然后

error: [Errno 9] Bad file descriptor

我想在聊天服务器代码中处理此问题，并始终保持运行，无论是客户端连接还是断开连接， 详细的例外是

---------------------------------------------
error is [Errno 131] Connection reset by peer
