OK - I have some debugging for the reaps: [25/Mar/2010:08:28:40 +0000] NSMMReplicationPlugin - _replica_reap_tombstones: removing tombstone nsuniqueid=2a83f601-1dd211b2-8055f995-55bd0000, [email protected],ou=blah, o=blah.co.uk because its deletion csn (4ba16da5000000660000) is less than the purge csn (4ba248bf000000660000). [25/Mar/2010:08:28:44 +0000] NSMMReplicationPlugin - _replica_reap_tombstones: NOT removing tombstone nsuniqueid=e173fa81-1dd111b2-809bf995-55bd0000, [email protected],ou=blah, o=blah.co.uk [25/Mar/2010:08:28:44 +0000] NSMMReplicationPlugin - _replica_reap_tombstones: NOT removing tombstone nsuniqueid=ac72a282-1dd111b2-80b1f995-55bd0000, [email protected],ou=blah, o=blah.co.uk [25/Mar/2010:08:28:44 +0000] NSMMReplicationPlugin - _replica_reap_tombstones: NOT removing tombstone nsuniqueid=f3f92e81-1dd111b2-80b1f995-55bd0000, [email protected],ou=blah, o=blah.co.uk It looks like it is generally purging the tombstones, but there is a growing number that it is not. I'm not sure what these deletion and purge csn's are and where I should find them? Thanks. Jim. -- 389 users mailing list [email protected] https://admin.fedoraproject.org/mailman/listinfo/389-users
