we are using freeipa in a 4way multi master replication setup. 

Servers ipa14,ipa15 and ipa34,ipa35 on

CentOS Linux release 7.3.1611 (Core) with version

ipa-server-common-4.4.0-14.el7.centos.7.noarch.

We have an issue where one of the servers log a missing CSN. It happens even after 

ipa replication reinitialized.

We are guessing that CSN 5a0a27d9000000060000 only exists on ipa35, but we see it in those files listed on ipa15 and the error is reported there.

Please see attached file with logs.

How can we fix this?
