Hi!
I am running OpenLDAP 2.4.47 with significant write activity (in the hundreds of modify/add/del ops per second), and a large volume of data compared to available RAM (about 20G)
For backups, I am trying to do a live slapcat dump to maintain availability, and encountered the growth in MDB database size described in those ITS:

I am however a little puzzled over the rtxnsize option. My understanding is that this option splits large read transactions (such as backups) into smaller transactions, allowing freed pages to be reused before the end of the full operation. This is critical for me because backups take more than 10 minutes and a significant portion of my MDB file (100G) gets filled up during that time.
The rtxnsize option only affects LDAP Search operations.
