Orchard CMS causing System.StackOverflow Exception in w3wp.exe

Question

I recently installed Orchard V1.8.1 via the Web Platform Installer. It was set up to run on .NET framework 4.0 Integrated mode and I could successfully run the installation script and even managed to log in and install the Metro theme.

However, since this morning, whenever I try to browse to the newly created site, it takes extremely long to load, or rather it doesn't load, my browser just keeps waiting for a response.

I RDP'd into the server and saw that each and every time I try to browse to the site, an error dialog pops up saying that "An unhandled Microsoft.NET Framework exception occured in w3wp.exe" And gives me the option of debugging using Visual Studio. When I do that I get an additional message stating that "An unhandled exception of type 'System.StackOverflowException' occured in mscorlib.dll".

This happens only for the Orchard CMS site. There are 5 other custom built sites running on .net version 4.0 integrated mode, though each with their own app pool, naturally.

Again, I don't get these errors in the browser, they're shown in my remote desktop session on the server.

Server details: X64 Windows server 2012, IIS 8.

Are you able to get a worker process dump you can analyse with WinDBG and SOS? (blogs.msdn.com/b/tess/archive/2008/03/31/…)? these are a great set of tutorials to get you started down the road of debugging gnarly stuff like this: blogs.msdn.com/b/tess/archive/2008/02/04/… — Kev

I had this exact issue, it turned out that I was trying to call the partial it was actually in, therefore getting into a loop.

So within my 'Parts/TabledData/Pagination' .cshtml file I had this:

@Html.Partial("Parts/TabledData/Pagination")

Hope this helps!
