Gateway Redundancy behavior Questions?

We have recently implemented redundancy within our system. A couple behaviors occurred when forcing to backup that seemed a little odd, just curious if they are expected.

  1. When making global changes to the Master, will the Backup disconnect from peer temporarily to update the changes? We noticed this today, it would say out of date on the Backup and the peer would be missing on the Master. After a couple minutes it regained its “peer connected status”.

  2. The backups are set to COLD. When the Master is active, we noticed our OPC-DA connections were cycling between Connected & Connecting about every 5-10 minutes on the Backups while the Master connections were solid. When running on backups they do not seem to cycle, they are solid as well when Backup is active. Is this expected behavior?

Any insight on these topics are greatly appreciated!
