This is going to be down to data expiration.  Does your activity log show
that expiration is running longer and expiring more.
Did you have the opposite pattern a while back where you database grew
over a short period.
What I find really useful for explaining where the data is expiring is to
keep periodic query occupancy files.
Then you can see by comparing the files which nodes are growing or have
lost the large number of objects to explain your shrinking database
