Sometimes, an alert in this article--typically DATABASE_CORE_SPACE_LOW--may trigger and clear automatically.

If the UI and performance metrics work, and the alert does not reappear within a week on the same appliance, it can be ignored. The alert clears itself because an internal operation automatically cleans up excess database capacity used when the alert initially appears.

Multi-appliance clusters may see this alert happen at least once on each appliance sometimes within hours or days of each other.

A dial-home case may automatically be created due to these alerts.
