I have recently been deploying a asp.net extranet application.
The asp.net worker process starts off with 30MB virtual memory and then upon
serving a few pages, the memory usage increases to a WHOOPIN! 200MB and
eventully the asp.net process restarts at 300MB and my application becomes
"unavailabl e" with my sessions being destroyed.
Is there an explanation why the asp.net process uses that much memory?
After i have logged out of my application and closed the browser, the memory
usage does not decrease?
Is this due to the Compiler keeping the cache of the application?
Is there anyway i tune the performance and find the memory leak?

do you access databases? do you close your connections?
do you add something in cache/session?
do you destroy your objects?

I am using Castle Proxy as an object factory to serve objects and store them
in an object pool for retrieval.
Other than that, our application uses very little session data, more for the
forms authentication.
Database:
Access MySQL database using nHibernate which manages the database pooling.

mmm...
its difficult to isolate the problem from my point of view ;-)
have you try to open 1 page only and refresh it a lot of time while
measuring the memory usage?
how many memory is installed on the server?
have you try to call the GC.Collect() method to purge the memory?
I have found a post regarding the usage of Strings instead-of StringBuilder
using strings can cause huge memory usage, changing it to stringbuilders can
help you.

All,
As I understand it, a single application (i.e. IIS virtual directory)
in ASP.NET may in fact have more than one corresponding
HttpApplicationState object (more or less one per server thread, I
think). During each request, only one of these objects is exposed to
the page as Page.Application. This seems to be supported by the fact
that when I use the debugger, I can see the Application_Start event
firing more than one time even...
