Hello,
I switched back to BDB and it works fine again. I also downgraded to Master-Slave to ensure the good working as suggested.
But my initial question is still unanswered. Yes ? No ?

Hello,
 I migrated my OpenLDAP data from bdb to mdb in a Multi-Master
Replication architecture that is working for years now.
 Unfortunately using only 2.4.31-2+deb7u2 from Debian 7.

Don't use MMR with that release.
