One of the major gripes I have with the Windows operating system is its inability to build decent event logs when an exception occurs. This is particularly annoying on the server builds because as a developer, I need to know what is causing a crash or a hang. Recently I have been developing a site using Sitecore and after a publish the site started crashing and bringing down the entire server. The following is an overview of how I solved the issue.

The first thing I did was check the Event Viewer on the server itself – notice the horrible information within the error. The one important code to write down is the exception code (0xE053534F).

After reading a tutorial on how to catch a crash I was able to catch the crash in a dump file. While the debug diag tool was useful for catching, I needed WinDbg to get to the root of the problem.

Note: I set the symbols location to SRV*c:\users\jsedlak\documents\websymbols*http://msdl.microsoft.com/download/symbols

As you can see, the debug view is fairly useless. Run the following commands:

• .loadby sos mscorwks
• !clrstack

Now you can see what is causing the stack overflow. Turns out it was an XSLT file that was doing a recursive climb up the Sitecore tree without a base case. The cause of the problem however was that I had just implemented Workflow on all items which corrupted their state and seemed to have removed their published version from the web database. By fixing the XSLT to have a base case and submitting all content through their workflow I was able to get the site back.
