Failure to scale down

• Because the scaling buffer values are set too high, there are more servers available than necessary.
• The shutdown TTL or delete TTL values are set too high. The higher these values, the longer it takes for machines to scale down. Refer to the machine life cycle.
• Empty game servers (that's, game servers without players) are failing to deallocate when a game session completes and all players leave the match. This prevents the machine life cycle from initiating the TTL timers until all the game servers are deallocated.
