I smell something fishy!
The number of cases (rows) is likely irrelevant.
4798 (are you sure there aren't 4797) is a rather odd request to submit to GLM.
Have you experimented to see at what point the thing crumbles?
4798*4798=23,020,804 covariance elements.  I suspect that would fit into about 200M.
If these are all continuous (scale) variables then who knows what the limit would be.
If they are categorical then the problem size grows exponentially if a full factorial (the default) model is inadvertently specified.
So, in your court.
MATRIX.
COMPUTE FATTY=MAKE(4798,4798,1).
END MATRIX.
No problem.  I am running 11.5 under Vista (win32) 4G RAM.

What for crying out loud are you doing which would conceivably require more than 16G.

David,
68.774.810 rows / 4798 variables -> GLM
