It was hard to read the code in the email. In the future, try using pastebin or some other service, or open a JIRA issue and put the code in there. I think I saw that a Dictionary was holding the children but it isn't a weak-reference dictionary, so that could pin those children in memory.

My thought is to execute this function prior to unloading each module. Towards that end I have created a function in the parentApplication called clearModuleEvents which recursively loops through each child, and if the "clearEvents " function exists, run it. Then I unload the module. Using the profiler when I execute clearModuleEvents, it seems to create another instance of each display object. I am not sure why. I would appreciate if someone might tell what might cause that.
