Sometimes, when trying to resolve replication issues, we end up with a newer message flooding the errors log from the replication plug-in:
"
changelog iteration code returned a dummy entry with csn 5385ee18000000070000, skipping ...
"
and there is no way to get rid of this messages that keeps filling the errors log file.

this is a report to find a way to try suppress this message when not necessary, in
ldap/servers/plugins/replication/windows_inc_protocol.c
ldap/servers/plugins/replication/repl5_inc_protocol.c

examples:

RHDS 9.1 RHEL 6.5 with

Description:

1. Can't locate CSN %s in the changelog (DB rc=%d).
   Print the message once per one missing CSN.
2. changelog iteration code returned a dummy entry with csn %s, skipping ...
   Downgrade the log level to replication log level (SLAPI_LOG_REPL).
