Thanks Bastian for your response. But I want to clear that I don't use slapadd while slapd is running. I have LDIF data which needs to be imported in the new Multimaster servers. That's why I used slapadd. When I did the import (slapadd) with the big data, it doesn't get replicated. To check the problems I did the import with single entry only.
It is not now, nor has it ever been, supported to do an offline add via slapadd on a master, and then magically expect that to replicate out to a consumer via syncrepl. Syncrepl is an active protocol (it replicates the changes that occur while slapd is running). If you are going to offline modify slapd on the master, you will have to do the same thing on the replicas, OR reload them via slapadd, OR trigger a refresh manually on the replicas.
