That's what recent versions of GNU ls do when they can't stat a file, for
example because you have no access.

This means there are no free vcache entries. Either there is a leak, or
you have more than 3000 AFS files in use. Try giving afsd a larger value
for the -stat switch.

You got 1.4.2 to build against 2.6.19? That's a neat trick. For 2.6.19
you should need at least 1.4.3rc1 (and you really want rc2, which fixes
some build issues and a nasty problem with clients crashing when a vlserver
is down, but that's not out yet).
