Hi, After an upgrade to Centos 7.3.1611 with “yum update", we started seeing the following messages in the logs: “”” May 9 21:58:28 inf01 ns-slapd[4323]: [09/May/2017:21:58:28.519724479 +0000] NSMMReplicationPlugin - changelog program - agmt="cn=cloneAgreement1-inf02.dev.ecobee.com-pki-tomcat" (inf02:389): CSN 576b34e8000a050f0000 not found, we aren't as up to date, or we purged May 9 21:58:28 inf01 ns-slapd[4323]: [09/May/2017:21:58:28.550459233 +0000] NSMMReplicationPlugin - agmt="cn=cloneAgreement1-inf02.dev.ecobee.com-pki-tomcat" (inf02:389): Data required to update replica has been purged from the changelog.

The log messages are pretty frequently, every few seconds, and report few different CSN numbers that cannot be located. This happens only on one replica out of 4. We’ve tried "ipa-replica-manage re-initialize —from” and “ipa-csreplica-manage re-initialize —from” several times, but while both commands report success, the log messages continue to happen. The server was rebooted and “systemctl restart ipa” was done few times as well. The replica seems to be working fine despite the errors, but I’m worried that the logs indicate underlaying problem we are not fully detecting. I would like to understand better what is triggering this behaviour and how to fix it, and if someone else saw them after a recent upgrades. The software versions are 389-ds-base-1.3.5.10-20.el7_3.x86_64 and ipa-server-4.4.0-14.el7.centos.7.x86_64 Thanks, Goran -- Goran Marik Senior Systems Developer ecobee 250 University Ave, Suite 400 Toronto, ON M5H 3E5 -- Manage your subscription for the Freeipa-users mailing list: https://www.redhat.com/mailman/listinfo/freeipa-users Go to http://freeipa.org for more info on the project
