Maybe you have too much device inodes to check but otherwise
uninteresting? In this case it is not proportional to the
amount of your storage.
The solution to this is either filter what you scan, or if you
can, you can try to either rm unnecessary files from /dev,
or tell your *scan programs to look at a different directory,
and polupate it only with the needed devices. At the worst
case you can do it by editing the path in the source and recompile.
