Hello.

I recently upgraded from 4.2.0 to 4.4.0 (CentOS 7), and am now seeing missing CSN errors, such as:

[26/Aug/2017:21:39:32.891818412 +0000] NSMMReplicationPlugin - changelog program - agmt="cn=meTo******.com" (******:389): CSN 597276fb0005000a0000 not found, we aren't as up to date, or we purged
[26/Aug/2017:21:39:32.893279073 +0000] NSMMReplicationPlugin - agmt="cn=meTo******.com" (******:389): Data required to update replica has been purged from the changelog. The replica must be reinitialized.

(server names removed)

These errors are showing up all over the place, and I have been "fixing" the problem by removing the broken links and setting up replication with a different partner just to get things flowing again.

I tried to re-initialize as the error suggests, but that didn't solve the problem. Is there a recommended process for resolving missing CSN errors?

Thank you in advance!
