Socket通讯的“System.Net.Sockets.SocketException (0x80004005)”问题

LonelyPause 2017-06-09 05:10:07

最近做了一个比较简单的SOCKET通讯的小程序，用于实现一个小功能。说白了就是接收数据，存入数据库。

但是在实际运行当中，却出现了一点问题，当程序运行一段时间（大约5个小时）后，就会报错：

System.Net.Sockets.SocketException (0x80004005): 由于系统缓冲区空间不足或队列已满，不能执行套接字上的操作。
在 System.Net.Sockets.Socket.BeginReceive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags, AsyncCallback callback, Object state)

已经查了三四天了，毫无头绪！

依照网上说的进行注册表设置也设置了，依旧不能解决问题。

望大手指教一二！

下面放出出问题的代码
