当我尝试在我的WCF客户端应用程序上传3mb或更多的文件时，我收到此错误。

您可能需要增加服务器绑定和客户端绑定上的配额。 http://msdn.microsoft.com/en-us/library/ms731078.aspx
如果服务器也是WCF服务，为了更好地诊断这样的事情你也可以enable WCF tracing at the server-side - 并且你会得到与运输配额等相关的错误以及服务日志中出现的其他奇怪的东西（其中您可以使用作为Windows SDK一部分提供的服务跟踪查看器附带的服务日志查看器进行查看。
有时您必须执行IISReset或“触摸”服务的web.config以强制它关闭服务跟踪文件，否则跟踪查看器无法查看日志中的所有活动。
