Lambda can try to terminate already terminated instances

The AWS api can return terminated instances for up to an hour. In cases of small server pool sizes, an instance that was already terminated could be returned to be "terminated" again.

No file or test is identified in the issue. Trace the JavaScript AWS Lambda flow that selects instances and requests termination, then check how the AWS API response is handled for instances already terminated. Done means the Lambda does not attempt to terminate an instance that has already terminated, including when the server pool is small.
