Re: SyncREPL Testing

["Jong-Hyuk" <jongchoi@OpenLDAP.org>]

test019-syncreplication-cascade performs a similar test, but it might miss
the reported case because it tests with a small data set. Configuration
files at the consumers / master will help to further examine the issue.
Also, it would be easier to track this if you file an ITS. Thanks for the
detailed info. - Jong-Hyuk
