Hi,
you're not showing the other side of the replication (Node1 replicating
from Node2). Also your logs suggest that Node2 considers cn=Cordys
CAPConnector,cn=cordys,cn=defaultInst,o=otxlab.net has been
intentionally deleted since the last time Node1 has updated it.

In general, unless you can reproduce a desync and have a (semi-)reliable
way of doing so that you can share here, please post to
openldap-technical as 99 % of the time an issue comes from operational
issues, not code. Closing this issue, please follow up there if you have
futher questions.

Regards,
