If you see the event “Data change rate beyond supported limits” in the ASR replicated items logs, you probably need to change the disk type of your managed disks for that Virtual Machine.
I would advise waiting a bit to check if the error disappears or remains consistent.

To change the disk size go to:
- Disks
- Select the disk specified in the error message above
- Click on Configuration
- Under Account type switch from “Standard HDD” to “Premium SSD” (or “Standard SSD”)
- Save
