One possible solution is to make a copy of the active file and retain an older
one and use diff to find the ones that were deleted.  Then its a simple matter
to remove the old directories.

Something like this should work:

cd $pathdb
cp active.1 active.2
cp active active.1
diff -c active.1 active.2 > active..tmp
grep '^- ' active.tmp
