Index was outside the bounds of the array - Active Administrator 6.x

The error “Index was outside the bounds of the array” is displayed either in the AA (Active Administrator) Console, or when attempting to create or open the database.

There can be multiple causes for this error, but typically the network connection to the database has been lost.  

Via the Active Administrator Server Management console go to the Start Page | Database Configuration and click “Test Connection”.

Verify that it successfully connects.

If it does not connect successfully, then check your connection to the network.

If the error persists, reboot the AA server when permitted in your environment.
