Without seeing your script and knowing the dir names in question, it's hard
to say, but the obvious bet would be some kind of shell quoting/escaping bug
in the way you invoke 'du'.

Rename it. How did you get a filename that's longer than PATH_MAX? That's
not meant to even be possible!

Probably perms again. Hard to know whether it's actually crashed or is just
doing something with no visible output unless you actually debug it though.

First two seem easy. Third is indeed a bug I would guess; if the tree walk
fails, it should fall back to manually descending the dirs (or at least
error-out gracefully). Would need to be able to reproduce it to know for

Let's see if we can't make 'du' work first!
Can't think of a witty .sigline today....
