I have an n-tier .NET enterprise application that is having some issues.

I'm utilizing three tiers.
Presentation - ASP.NET web application
Business - .NET class library using Enterprise Services and COM+
Data - SQL server 2000

The presentation instantiates components from the business tier, does what
it needs to do and then disposes of the object using .dispose. Event
tracking is enabled on the COM+ app components, and all objects show 0
instances being held after the method called is finished executing.

The issue is that when the com+ app in the business tier is first called, a
dllhost.exe is started with a memory allocated around 15,000K. The first
request to the create an instance causes the memory to jump to 19,000K and
then with every additional call to the component, the dllhost.exe increases
in memory until the server falls over... Its as if the memory allocated for
the objects in com+ are never being released once instantiated.

Does anyone have any suggestions?

Thank you.
