I have set up delta-syncrepl between provider A and consumer B, and it seems to work ok. Online updates to A are synch'ed to B. However, about once a month, there is a large update which contains hundreds of million records. Online update is going to take days. I tried to bring A offline, do slapdadd, and bring A back online. But these new entries were not synch'ed to B. Is there a way I can make this work?

Thanks,
Khoa
