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

问题描述

我occasionaly从AJAX.NET应用程序获得以下弹出

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

从 Microsoft知识库的状态code表示ERROR_INTERNET_CONNECTION_RESET，但它没有说明究竟是什么潜在的问题引发了错误摆在首位。

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.

我如何登录/跟踪/等生成弹出的基本错误？

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

推荐答案

这是一个视图状态的问题，但不随时间而与尺寸有关。尝试在你的web.config用的maxRequestLength玩。

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