Sys.WebForms.PageRequestManagerServerErrorException 12031 [英] Sys.WebForms.PageRequestManagerServerErrorException 12031

问题描述

我偶尔从AJAX.NET应用程序获取以下弹出窗口

 Sys.WebForms.PageRequestManagerServerErrorException：处理请求时发生未知错误服务器。从服务器返回的状态代码是：12031 

从 Microsoft kb 状态代码指示ERROR_INTERNET_CONNECTION_RESET，但是它并没有说明触发错误的根本问题是什么。首先，

如何记录/跟踪/ etc生成弹出窗口的底层错误？

解决方案

这是一个viewstate问题，但是与时间无关，但与大小无关。尝试在您的web.config中使用maxRequestLength。

I'm occasionaly getting the following popup from an AJAX.NET application

Sys.WebForms.PageRequestManagerServerErrorException: An Unknown error occurred while processing the request on the server. The status code returned from the server was: 12031

From the Microsoft kb that status code indicates a ERROR_INTERNET_CONNECTION_RESET, but it doesn't state what was the underlying issue the triggered the error in the first place.

How can I log/trace/etc the underlying error that generated the popup?

解决方案

It's a viewstate problem, but not related with time but with size. Try playing with maxRequestLength in your web.config.
