Insufficient DB instances available

Focus mode
Insufficient DB instances available - Amazon Neptune

The InsufficientDBInstanceCapacity error can be returned when you try to create, start, or modify a DB instance. It can also be returned when you try to restore a DB instance from a DB snapshot. When this error is returned, a common cause is that the specific DB instance class isn't available in the requested Availability Zone. You can try one of the following to solve the problem:

  • Retry the request with a different DB instance class.

  • Retry the request with a different Availability Zone.

  • Retry the request without specifying an explicit Availability Zone.

For information about troubleshooting instance capacity issues for Amazon EC2, see Insufficient instance capacity in the Amazon EC2 User Guide.
