This entry is a slightly updated re-post of an article found on my personal blog.
Recently we had a site that was getting ready to go live, hosted on a 64-bit version of Windows Server 2008 (IIS7). I won’t bore you with all the details of all the issues we worked through but we had one nasty issue that, as soon as it occurred it brought the server down; 100% CPU usage by the w3wp.exe process and memory usage steadily climbing. Our error logger was catching primarily one xml argument exception (but with a few variations).
