Hi, This morning we ran into a problem after updating 386-base to 1.4.4.17 (hoping to solve a trimming [1] issue). The ns-slapd server ended up in a deadlock so I had to revert. Since then we have ipahealthcheck reporting CRITICAL "is not in synchronization" errors. Also, in one of the replica's there is a message "Incremental update failed and requires administration action". Although I'm the administrator myself I wasn't quite sure what to do. Somewhere I read that I should do a re-initialize. One of the three replica's/masters is still behaving normal (I hope). So I took that one as the source for the re-initialize. I did do bot commands ipa-replica-manage and ipa-csreplica-manage with re-initialize. Both commands succeeded. However, ipahealth check keeps complaining. I would like to know where else I should look to figure out the problem.
