Ok. I've increased nsslapd-db-locks to 20000 and reduced 
nsslapd-changelogcompactdb-interval to 3600 in cn=changelog5,cn=config to see 
the changelog free event more frequently. No change. I have still : 

[19/Jun/2015:10:36:46 +0200] - libdb: BDB2055 Lock table is out of available 
lock entries 
[19/Jun/2015:10:36:46 +0200] NSMMReplicationPlugin - changelog program -
