In a master/replica environment, sync replication causes a massive explosion in database size on the replica.

For example, with a 25MB database, the size on disk grew from 25MB to 50MB in the space of an hour (and it shows no signs of slowing down). Entries in the freelist grows without reducing:

[zimbra@ldap02-zcs ~]$ mdb_stat -f data/ldap/mdb/db Freelist Status Tree depth: 2 Branch pages: 1 Leaf pages: 43 Overflow pages: 0 Entries: 987 Free pages: 7441

In monitoring, it appears every change adds about 6 entries and 40+ free pages. id2e database looks the same as on the master.
