本文记录了一次解决WebSocket通信中断问题的过程。客户端调用WebService时出现System.IO.IOException，原因是远程主机强迫关闭连接。服务端报错显示Axis2在发送SOAP响应时发生错误。经过排查，发现当返回的XML数据过大时，可能导致Socket连接超时或中断。通过减少数据量和适当增加超时时间，成功解决了该问题。结论是WebSocket不适合大数据传输。

最近遇到一个比较棘手的问题：

问题是这样的，搭建了一个webservice的服务平台，让后提供给多个接口调用，有两家接口调用了同样的一个方法，但是第一家的接口从来没有出现过问题，而另一家就奇怪了，最近总是出现 socket通信中断的情况，客户端报错如下：

调用WebService时找不到方法：doDownloadRecipeInfo。原因：System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. ---> System.IO.IOException: Unable to read data from the transport connection: 远程主机强迫关闭了一个现有的连接。. ---> System.Net.Sockets.SocketException: 远程主机强迫关闭了一个现有的连接。

而在服务端报错为：
