Working with a large document (>2GB) Lots of images. 
The last successful save was at 2.61GB
As I added to the document it would no longer save successfully.
Got following error message:

3.

Actual Results:
Error message:

Additional Info:
As a workaround, so I don't loose my work, I broke the document into two smaller documents (1.4GB & 1.29GB) which I am able to save normally.
FYI: I am able to edit and print the combined document without issue. It's just that I cannot same it.

How many images and pages do you have in your document? (you can see the amount in Navigator)

What image format do you use? PNG? BMP? TIFF?
