Hi

I get an System.AppDomainUnloadedException: Automation error
error when the webserver has been running for a while.

I'm running on windows 2000 Microsoft .NET Framework Version:1.1.4322.573; ASP.NET Version:1.1.4322.573.

I've changed in machine config <processmodel>, it will not time out.


The page header <%@ Page Language="vb" validateRequest=false aspcompat=true AutoEventWireup="false" ...

On one server it occurs randomly, while on the other server it fails everytime after the first time.

Its accessing an vb 6 dll through interop using early binding.

here is a stack trace for one of them

[AppDomainUnloadedException: Automation error]
Microsoft.VisualBasic.CompilerServices.LateBinding.LateGet(Object o, Type objType, String name, Object[] args, String[] paramnames, Boolean[] CopyBack) +895

What could be wrong?

as your VB6 component run in STA mode ,
you must declare
<%@ page AspCompat = true %>
on head of your .aspx file;

or you can set "this.AspCompatMode = true" in page OnInit event handler

Hi
well its already there
<%@ Page Language="vb" validateRequest=false aspcompat=true
AutoEventWireup="false"
 
maybe you should check your vb6 component.
do the components work well in classic asp application?
