My immediate thought was a memory leak problem (too many mallocs as
compared to the number of free statements). Disk? I would have thought
the computer system to be radiation shielded CMOS (or modern variant)
throughout. Cripes, I get disk problems first and foremost on the
systems I use.

Do you know for a fact that this system has a disk? Since the working
software is completely static (except for bug fixes from earth), it's
memory requirements are fixed and known, and ROM alone should be
sufficient.

I would also expect the delicate moving parts of a disk drive to be
extremely sensitive to the comparatively violent landing process of bounce-
and-roll. I wouldn't want disk drives to be subjected to that trauma, if I
were the designer.
