Hi, This usually indicates a resource leak. But can also happen if you stress the system particularly on purpose and then run the converter. This page gives a good explanation of when this can happen: http://weblogs.asp.net/fmarguerie/cannot-create-window-handle-desktop-heapTo check if you have any handle leak, go to Task Manager and enable GDI Objects, Handles, Threads and USER objects columns and see if you see unusual consistent growth in any of those before this happens. If you do notice a handle leak and you believe it is related to us, please try to isolate the problem into a test project and then send the test project to us. We will investigate further as soon as we receive it. Thanks!

Hi,
Sorry for delay on updating status. Still we are getting same error. We tried in our test environment and observed Task Manager. We observed that while running this process in TEST it consuming more resoluces on server. Its keep on increase respurce consumption and after certain limit reached it throws above mentioned error. I can share code we are running.
Thanks.

Hi, We will need you to isolate the problem into a test project so that we can run it here to see the problem. Usually as soon as we can see the problem here, we will be able to find out the root cause. Please see here for more information on how to submit a test page: http://www.essentialobjects.com/forum/test_project.aspxThanks!
