dds overlay on mirrored master

Hi,

I'm running a mirrored master server and several read-only replicas. Now I want to deal with dynamic objects, so I enabled the dds overlay. Because the config is mirrored, the dds-state is TRUE on both master servers. In my syncrepl statement I set schemachecking=off and exattrs=entryTtl,entryExpireTimestamp. The replication of dynamic objects is working.

My question is: will there be a conflict when both master servers are trying to delete expired objects at the same time? What's the best way to configure the dds overlay on a mirrored master?

Thanks in advance. Dirk
