DLL not running in separate memory space on IIS server

I have created a webclass DLL and deployed in an IIS server. It is working fine when I access the site from any other machine using IE.
When I set the directory property to run in separate memory space and try to access from the remote mechine it hangs the server. When I go the task manager in server It is found that MTX.exe is running occupying the available memory and CPU.

I had to restart the server to regain control of the server.

D0 I have to change some settings in my application or is it some code in my application that is creating the problem.

Advance thanks
