When the control loads a document, it first needs to open the file and obtain its stream. When the file is too big, its stream hits the limitations of the platform, cannot be accommodated in the dedicated memory and an OutOfMemoryException is thrown. What I can suggest in this case is to change the platform type of the project to x64 so that the application can have access to more memory.
Hope this is helpful.
