Umm... what bug? :-)
With 1.5 million leases you use 533 Mbytes memory, with just 2558 leases
you use 35 Mbytes memory. That's not a bug.
What you want sounds like some way of actively denying clients with
specific addresses without creating leases for them. I can't from the
top of my head think of such a way with ISC DHCP, but I'll give it a
try.
