When does the application placement controller stop a server?

The application placement controller stops a server for the following reasons: • A memory constraint on a node exists. The application placement controller understands the minima for the dynamic cluster, or the amount of capacity needed for that dynamic cluster and the processor constraints and memory constraints of the system. If available memory becomes low on a node, the application placement controller attempts to stop instances to try and prevent the node from swapping. • The dynamic cluster is configured for application lazy start and proactive idle stop, and no demand exists for the dynamic cluster. If the dynamic cluster has no demand, the application placement controller attempts to stop instances of that cluster to eliminate the resource consumption of an inactive dynamic cluster.
