Physical memory control that uses the resource capping daemon is an optional feature. The resource capping daemon rcapd regulates the consumption of physical memory by processes that run in projects that have defined resource caps. Associated utilities provide mechanisms for administering the daemon and reporting related statistics.
For additional information, see Chapter 10, “Physical Memory Control Using the Resource Capping Daemon (Overview),” in the System Administration Guide: Solaris Containers-Resource Management and Solaris Zones.
