MMR - Add and delete entry on on server, CSN too old on the other and the entry is not deleted

["Meunier, Antonin" <antonin.meunier@cgi.com>]

Hello,

I'm with openldap-2.4.39.
I've 2 openldap server on MMR, the config is down to the mail.

On the 1st server, il made 
- ADD an entry
- Little after (1h) DELETE the same entry

On the second server, I have : 
- The entry is created by replication
- BUT the entry is not delete by the replication with a CSN too old error.

How can i resolv this ?

Thanks by advance
