would be nice to include the problem description again, but if you are 
referring to:


[26/Aug/2017:21:39:32.891818412 +] NSMMReplicationPlugin - changelog 
program - agmt="cn=meTo**.com" (**:389): CSN 
597276fb0005000a not found, we aren't as up to date, or we purged
[26/Aug/2017:21:39:32.893279073 +] NSMMReplicationPlugin - 
agmt="cn=meTo**.com" (**:389): Data required to update replica 
has been purged from the changelog. The replica must be reinitialized.


there is no magic command to resolve it.
In a replication session the supplier compares its own RUV with that of 
the consumer and for each replicaid in the RUV decides if there are 
changes to send and what is the starting point to send changes and the 
minimal starting csn is used to position a cursor in the changelog.
If this change is not found you get an error like the one reported. The 
message is from Aug,26th and the missing csn is from Jul,21st - so it 
could very likely be that the csn was purged or the changelog recreated 
in between. Maybe the replica with replicaid "000a" == 10 was 
remomed/recreated or ...


Now, why do you see these messages now ? In previous releases 389-ds, if 
a csn could not be found silently chose another starting csn, or if that 
failed stopped replication. Now we handle the missing csn as transient 
error, the missing changes could be sent to the consumer by another 
server and the staring csn would move and could eventually be found.


What to do. Investigate the RUVs of the servers, check what is the 
status of replica 10, eventually a cleanallruv for this replica would 
resolve the problem. If 10 is still a valid replica ID probaly servers 
have to be reinitialized.


There is also a possibility to enforce the previous behaviour and pick 
another starting csn, add the following to teh replication agreement 
failing:

replace: nsds5ReplicaIgnoreMissingChange
nsds5ReplicaIgnoreMissingChange: once
