It doesn't look to me like your replica is replicating at all. Have you done a slapcat of the two and verified they are identical?

Ok, then I did a slapcat on a replica and to my big surprise, before I did the slapcat, bdb files on the replica were very small, then as soon as I did the slapcat (while slapd is off), now they are similar in size to the master !? Do we need to run regularly slapcat on replicas in order to "really" replicate ?
No. It sounds like you don't have a checkpoint directive set for your database. You should fix that.

You are right, now that I added checkpoint 200 240 in the slapd.conf, bdb files are bigger !
in fact my old repicas in 2.3 had that directive in global configuration whereas apparently in 2.4 that directive must be in a database definition, that's probably why I missed that one during the migration process .
thanks .

It had to be in a database definition in 2.3 too. But slapd(.conf) has always been kind in re-arranging things for the admin so they make sense.
