This might be a known issue.

However this would only fit if you are using an old MIP SDK, let me recommend as a first step; if you do not already have the newest MIP SDK please use it.

The issue I suspect this to be.. https://developer.milestonesys.com/s/question/0D50O00004zPVuc/why-is-the-imageviewerwpfcontrol-not-disposed

What are you using; ImageViewerControl or ImageViewerWpfControl?

What is the application doing when this is happening – shutting down, deleting an image viewer, changing camera, etc?
