problems with aspnet_wp memory usage

[Michael]

Hello all,
I have an ASP.NET application that generate pdf files.
I'm having problems with the "aspnet_wp", even when not generating the pdf files (the application generates a 700Kb pdf files), just while navigating into the website, the "aspnet_wp" start growing and growing but never releases the memory until I get an "out of memory" error.
The application was developed in .NET 2003, with Framework 1.1, C# and the component that generates the pdf files.

The strange thing is that the COM component i'm using, does not contain a "dispose statement", do you know a better way to destroy a COM component that does not have a dispose method ?

I am using this line of code to destroy the pdf generator object

System.Runtime.InteropServices.Marshal.ReleaseComObject(ObjectName);

I read that this could be a problem of the Framework 1.1 that has this kind of problem, but I read too that installing the Service Pack 1 for Framework 1.1 the problem could be solved.
I've installed the SP1, but I didn't see any difference.
Does anybody know how can I solve the problem of memory leak from my website ?

Thank you all

What development tool was used to create/build the COM component? If this is an ActiveX DLL then you may want to consider running it as a configured component (under COM+).

Hi Paul,
Thank you for the advice, I will try it.
I would like to improve my coding, so I would like to know if you know about a good (and free if possible) tool that would help me analyzing my code to check where it can execute hight memory consuption code ?

Thank you for your help

I'm afraid I can't suggest anything. I don't know of anything free and there isn't any product that I use to do this.
