Are these leases that have been superceded by later entries for the 
same address, or just leases that are old and expired ?

If it's the former then something is wrong. If it's the latter, then 
it's normal as all old leases are kept - in their most recent 
version. Ie, when a client renews, then a new lease record is 
appended - and when the cleanup occurs, the old record will be purged 
so that only the most recent is left.

How big are your pool declarations ? It sounds like they are large.
