Too many files in Spirit?

Nasa scientists say hundreds of computer files that have accumulated on the Mars rover Spirit may be the cause of problems that have crippled it. [BBC News]

Well, I won't claim I've never been involved in computer systems that had a problem due to running out of disk space... :) Still, for the money they've spent on the development of these rovers, one would think they would have the resources to test for this kind of thing in advance.

Let's hope "too many files" is the problem, because that really has a decent chance of being fixable from the ground.
