Hello everyone. 

Periodically and seemingly at random our replicas crash with the above error. Dirsrv shows as stopped and restarting doesn't help.
Someone suggested earlier that this is due to problems with topology plugin but I don't think that the cause as we are still on

I'm not sure if it's a problem with 389ds or with some other part of freeipa. The only other clue I can think of is that often we see inconsistencies
between replicas. IE a user that is supposed to be present everywhere goes missing on just one of the many replicas. 

I'm quite at a loss on how to troubleshoot this further. I hope that someone can assist.
