Ah, my bad, there are a total of 4 nodes, and while technically I guess they could all be "masters", only two of them ever receive writes, one is the primary behind a hardware load balancer and the other is the secondary; so in my head I have two masters and two read only systems. Which I suppose isn't really accurate from an openldap architecture perspective, sorry.
ITS#8444 (ignore the ITS title, it has nothing to do with memberOf), where there are out of sync problems with 3+ MMR nodes and delta-syncrepl when syncprov checkpoints.
Oh, I remember that ITS, I thought I'd fixed that issue by getting rid of the memberOf overlay and switching to dynlist 8-/. It seems since I stopped paying attention to it it's moved on in other directions.
I see there was a proposed patch posted on 8/25 that's been applied to RE24, I'll add that to my system and see if the issue goes away. Am I correct in my assumption that the patch only needs to be applied to the system that is receiving the updates?
I'd apply it everywhere you have syncprov configured, these could send a cookie with too little information for a replica to spot and skip a duplicate.
