The status code returned from Server was: 12031
Posted on 2012-08-16
Recently the website which was working fine started throwing this error on one of the user's machine when the user clicks the button on a page . All the controls in this page are wrapped inside an update panel and at the top level ToolScriptManager is present
Sys.WebForms.PageRequestManagerServerErrorException: An Unknown error occured while processing your request on the server. The status code returned from Server was: 12031
The web page is not having much data and i am not storing any data in view state(as this was the cause mentioned in earlier threads).I cross checked the httpRuntime tag in web.config and it as below.
<httpRuntime executionTimeout="210" maxRequestLength="102400" requestLengthDiskThreshold="80" useFullyQualifiedRedirectUrl="false" minFreeThreads="8" minLocalRequestFreeThreads="4" appRequestQueueLimit="5000" enableKernelOutputCache="true" enableVersionHeader="true" requireRootedSaveAsPath="true" enable="true" shutdownTimeout="90" delayNotificationTimeout="5" waitChangeNotification="0" maxWaitChangeNotification="0" enableHeaderChecking="true" sendCacheControlHeader="true" apartmentThreading="false"/>
Can some body help with this issue or give some clue what might be appropriate place to look for to fix this issue. I googled and few threads mentioned that it is WinInet API Error with the status code mentioned as
The connection with the server has been reset.
Has it got something to do with the network connection on which the user machine was , or is it related to the page that thrown this error..?
