I am testing a group and they seem to be havng a memory leak. Opening the
page code below is eating up about 10 meg an hour. I am going threw it now to
try to find out what is going on. I a bit rusty with .net been waiting for
the next big release.
All service patches are up to date. What other things should I look at.

The DesktopDefault. aspx page is used to load and populate each Portal
View. It accomplishes
this by reading the layout configuration of the portal from the Portal
Configuration
system, and then using this information to dynamically instantiate portal
modules
(each implemented as an ASP.NET User Control), and then inject them into
the page.
