Hi- First of all, I hope I am not rehashing a topic that has been endlessly discussed. I know that syncrepl gets discussed a lot from my searches, but I have not found a specific topic on my issue. I started out with OpenLDAP 2.3, with a single provider and two consumers doing syncrepl using a refreshAndPersist type of replication. Periodically, I would see that one or more of the consumers would fail to synchronize a change made to the provider. A restart of the consumer would fix this and we could move on. It was annoying, but not critical at this point. Since then, I have become more dependent on OpenLDAP and syncrepl. I have upgraded to 2.4 to try to fix the replication issue, but it seems worse than ever. I now have one provider and six consumers. The consumers randomly fail to synchronize (as evidences by contextCSN monitoring). This happens several times a day. I'm thinking that maybe there is something wrong with my configuratiuon. This is what I am using: Provider: overlay syncprov syncprov-checkpoint 1 10 syncprov-sessionlog 100 syncprov-nopresent TRUE syncprov-reloadhint TRUE limits dn.exact="cn=replica,o=users,dc=domain,dc=com" time.soft=unlimited time.hard=unlimited size.soft=unlimited size.hard=unlimited Consumers (all consumers have the exact same config): syncrepl rid=123 provider=ldap://ldap.sea.corp.domain.com:389 binddn="uid=replica,o=users,dc=domain,dc=com" bindmethod=simple retry="10 +" credentials=secret searchbase="dc=domain,dc=com" schemachecking=off type=refreshAndPersist interval=00:00:00:05 updateref ldap://ldap.sea.corp.domain.com A few "weird" things: * After the upgrade, I notice that the Directory Type on the Root DSE is still OpenLDAP 2.3 * I notice that where previously I could simple create a new consumer by installing a fresh copy of openldap, copying the config from another consumer over, and starting up to get a full copy of the directoy, it now fails to completely replicate and I have to do a full slapcat/slapadd to do the initial population. Like I said, I hope it's just something stupid I am doing...
