.Net Runtime Optimizatic

[na]

After installing AJAX 1.0 RC on my Windows 2003 server, I run into the
following errors when requesting an ASP.Net 2.0 page that transforms
XML data with XSLT. The XML data is of size 5MB and the XSLT is only
5KB. After several transformation, the IIS server will be shutdown
with "Service Unavailable". The problem does not occurs on ASP.net 1.1
application resideing on the same IIS server on a different port. I
suspect these errors may have something to do with the AJAX and ASP.Net
2.0. Please help.
