We have upgrading an existing ASP.NET 1.1 We application to ASP.NET 2.0 using
the migration tool.
While we had no problems with IIS Worker Process Threads with the 1.1
version, as soon as we did the upgrade we started getting intermittant
W3wp.exe errors stating that the worker process either could not read or
could not write to a particular memory location.
We are getting numerous errors in the event log like:
-----------------------------------------------------------
Faulting application w3wp.exe, version 6.0.3790.1830, faulting module
webengine.dll, version 2.0.50727.42, fault address 0x00002fec.

This error occurs regularly on our high demand web server and less regularly
on our deployment server and each of our development servers. It has only
occured since we installed ASP.NET asd Visual Studio 2005.
The website is in main the standard sort of stuff. We do use httphandlers to
intercept requests for images and web requests and stream a lot of content
directly from SQL databases.
Any thoughts to the possible cause and how we can go about isolating it?
