Server Too Busy in vs2012

Question

I've got vs2010 and vs2012 installed side by side. If I open up our MVC site in vs2010 and run it using the development web server it works fine, if I do the same thing in vs2012 I get "Server Too Busy" every single time for the first request to the site. Every request after the first request works fine.

Update: I've noticed in vs2012 it only happens of the project needs to build. If I haven't made any changes, ie the project doesn't need to build and I hit F5 to start it up and open up IE it works fine and I don't get the "Server Too Busy" message in the browser.

Answer 1

I have had this problem for my ASP.Net solution as well. There were no solutions for this problem on Stack Overflow or anywhere else.

Setup:

Visual Studio 2013 (but I think it will also work for vs 2010/2012 ASP.Net web application IIS express setup).

Our production environment never had this problem because it was running on IIS.

I have tried a lot to fix it, but I found one specific solution. I set the delayNotificationTimeout to 20 seconds, instead of the default of 5, which was not enough for our solutions to conjure up everything it needed to successfully run.

<system.web>     <httpRuntime maxRequestLength="104850"                   executionTimeout="600"                   enableVersionHeader="false"                   delayNotificationTimeout="20" /> </system.web>

just clean the solution before you build it. Also, check the size of the folder in which the solution is, before & after clean build; you will surely find some difference. Doing this ensures that you clean/remove unnecessary dlls created after every build which is the cause of delaying the normal flow.
