If you see this again, try this: Shutdown m3, then start it with the replica log level: cd /opt/fedora-ds/slapd-m3 ./stop-slapd ./start-slapd -d 8192 Then shut it down as soon as you see the replica_check_for_data_reload: error message. Then paste the error log to pastebin.com or rafb.net/paste and paste the link here.

To get up and running again, try this, assuming you have no pending changes in the m3 database that you care about: shutdown m3 remove all of the files in the changelog directory (e.g. /opt/fedora-ds/slapd-instance/cldb) restart m3 do a replica reinit of m3 from one of the other masters > > Thank you.
