Ok, thank you

Ok, what brought this up is that about every week, one of the machines in our
environment breaks the replication with messages like this:
[01/Nov/2017:17:12:52.815891904 +0000] agmt="cn=meToXXXX" - Can't locate CSN
59f9d98a000000760000 in the changelog (DB rc=-30988). If replication stops, the
consumer may need to be reinitialized.
[01/Nov/2017:17:12:52.820619690 +0000] NSMMReplicationPlugin - changelog
program - agmt="cn=meXXXX": CSN 59f9d98a000000760000 not found, we aren't as up
to date, or we purged
[01/Nov/2017:17:12:52.828626595 +0000] NSMMReplicationPlugin -
agmt="cn=meToXXXX": Data required to update replica has been purged from the
changelog. The replica must be reinitialized.
So it made me think that perhaps the CSN record is removed too early? The ’76’
in the CSN is the machine having the problem. What do you think could cause
problems of this kind?

Yep, found that info previously, but thank you still!
