-----------------------------------------
AFAIS upon MemberTerminatedEvent it's getting removed (check
MemberTerminatedEventListener).

> Scale down logic does not execute as intended
> ---------------------------------------------
>
> Key: STRATOS-614
> URL: https://issues.apache.org/jira/browse/STRATOS-614
> Project: Stratos
> Issue Type: Bug
> Components: Autoscaler
> Reporter: Imesh Gunaratne
>
> According to a flow test carried out on the latest code base, scale down
> functionality does not work as intended.
> Scenario:
> 1. Partition Max Instance Count set to 3
> 2. Send a sample request load to take scale up action. Autoscaler will spin
> up 3 instances.
> 3. Stop the sample request load.
> 4. Let the service cluster scale down.
> 5. One instance being terminated but two remains.
> As found in the Autoscaler logs Member Stat Context of the terminated member
> is not being removed from the Cluster Context. As a result the same member
> being selected in each scale down action round.
