Question

今天我被服务器监视器服务发出的警告文本消息唤醒，我的一台服务器已关闭，并且已经过去了7个小时。

服务器运行IIS中托管的WCF Web服务。

我在IIS中检查过我的应用程序池已停止。服务器上的事件日志中没有任何内容。

我的应用程序捕获所有错误并将它们写入文件系统。我看到有超过7300 FileNotFoundException份报告。他们都看起来像这样：

System.IO.FileNotFoundException("Could not find file 'C:\Windows\TEMP\fmhq0eve.dll'.")

at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage4(MessageRpc& rpc)
at System.ServiceModel.Dispatcher.MessageRpc.Process(Boolean isOperationContextSet)

我看到过去在StackOverflow上报告了这个错误，并且有多种原因，主要与Serializer缓存有关，但堆栈跟踪中的代码完全由WCF处理。

服务器完全独自待了一个多月。最后一次Windows Update重新启动是在21天，这些异常发生前5天。我想不出其他原因。

为什么这个问题开始发生，我们可以做些什么呢？这是WCF中的错误吗？

Answer 1

让网络服务可以访问C：\ Windows \ Temp文件夹使用iisreset重置iis

这应解决问题

CSharpCodeGenerator“无法找到文件C：\ Windows \ Temp \ ... dll”
