错误：System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host
System.ServiceModel.Channels.SocketConnection.Write(...)
在客户端向服务器端发送消息时，SocketConnection.Write。这个错误也不是一直出现，是1天内偶尔会有几个。现在使用的是NetTcp长链接，12小时空闲未使用关闭。有个自定义连接池30个。

也许是网络问题吧，不是提示超时了么
不是超时。

可能是网络问题出现包问题，也可能是TCP通道状态变更时产生的，现在不确定，也模拟不出来，极偶尔才出现。
@chinaspx: 检查下服务端压力（线程数），中间负载均衡是否开启了自动关闭连接等类似机制。

网络掉包 可以用 ping -t ip 测测
或把 netTcpBinding的
listenBacklog和maxConnections 配置大点，如 500 ，200
试试
这2个值从开始用服务器端配置一直是1000。并且我之前测试了，故意将这2个值设置小，客户端多线程并发调用，是报错，但这不是这个错误（及不是我问的这个问题）。
我现在怀疑是服务器端在关闭空闲连接时，客户端正好调用，但我模拟了，也没模拟出来这个错误。
所以现在这个错误还是未知，因为这是极偶尔在不知道什么情况下出现的。
StackOverflow 也没有理人呀，my god.

每次调用WCF时，有没有及时关闭释放信道。

你写一个简单的例子，~client for 循环（1000） 请求server，不要关闭信道， 看是不是也报这个错误
在不改任何配置下 我记得在第400次请求的时候 就会挂了，如果关闭信道，可以一直循环下去
