Assuming that the file's size converts 1:1 into
the variable's memory footprint, you are close
to the 4G (= 2^32) limit and your matrix then
occupies 37% of the total address space.  If you
duplicate your variable for some reason, 74% are
occupied, and you cannot create a temporary of
it anymore.  This duplicate might be the reason
why you "sometimes" cannot save it.

Maybe clearing the superfluous instance(s) of your
huge matrix can help, however, this is not a
real solution for your problem.
