Hi,

We've got some serious problems with randomly "Request timed out" error in some cases on our web application during requesting Telerik.Web.UI.WebResource.axd.

In some circumstances the request to Telerik.Web.UI.WebResource.axd is processed more than 2 minutes, in each case (when hit the page with Telerik on it) and it times out. Due to that, CPU Load increase to 100% (there are many requests to Telerik.Web.UI.WebResource.axd which waiting to be handled), and the effect is massively disaster - Users cannot use the application because it's overloaded.

In such situation - IIS Reset sometimes help, sometimes not.

It occurs 4 times in last month, and this issue is taking about 2-4 hours every time when it occur. After that - the request to Telerik.Web.UI.WebResource.axd is processed normally. I'm not sure if the traffic has something to do with it, because it occurred once after 9PM (the biggest traffic is approximately during the day).

What's the most funny thing - this request which is in some circumstances "Time Out" weight 12,4 KB, and contains Telerik controls CSS styles.

In attachment - some pictures with errors. We're using the Telerik version: 2013.2.611.40
I would be grateful for any help, because we're running out of ideas, and yesterday this error blocked our application for all day :(

Greetings,
Marcin

You can add following code to increase the time out and download size in web config for Telerik.ReportViewer.axd
  <!-- By Pawan to increase telerik controls export timeout -->
  <location path="Telerik.ReportViewer.axd">
    <system.web>
      <httpRuntime maxRequestLength="20480" executionTimeout="600" />
    </system.web>
  </location>
