March 14, 2019 – Alert: Data Integrity Issue with Mirror Database Catchup
InterSystems has corrected a defect in our mirroring technology that can result in inconsistency between mirrored databases. This defect exists for currently released Caché and Ensemble versions beginning with 2017.2 and for InterSystems IRIS Data Platform version 2018.1.
When the issue occurs, some journal updates are not applied to a mirrored database on the backup mirror member or an async member that is being caught up.
