    problems with aspnet_wp memory usage

    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+).

    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.
