I recently upgraded my CentOS7 machine to the latest el7.1 updates, and had oomkiller trigger in the middle of yum upgrade.
I managed to recover by doing a number of things including restoring dirsrv's data/config from backup and re-running ipa-upgradeconfig, followed by an ipa-replica-manage re-initialize from a known-good machine. Now, when I start up ipa, everything seems to be in sync data-wise, but in dirsrv's error log, I see this: [21/Aug/2015:12:45:50 -0400] NSMMReplicationPlugin - agmt="cn=masterAgreement1-ipa2.opennms.com-pki-tomcat" (ipa2:389): Missing data encountered [21/Aug/2015:12:45:50 -0400] NSMMReplicationPlugin - agmt="cn=masterAgreement1-ipa2.opennms.com-pki-tomcat" (ipa2:389): Incremental update failed and requires administrator action I fear this means that something is still not properly in sync and will eventually come back to bite me. Any ideas what's going on here, and how to fix it? -- Benjamin Reed The OpenNMS Group http://www.opennms.org/
