Memory Management Overview

The system performs most memory management tasks automatically. The system allocates some memory permanently and some memory temporarily. When applications are deleted, memory that the system assigned temporarily becomes available again.

The system releases available memory on a switch route processor (SRP) module or line module automatically if that module requires extra memory for an application. However, you can force the system to release available memory on the primary SRP module if you issue either the show processes memory command or the show utilization command.

For information about the show processes memory command, see Monitoring Memory-Related Resources Used by the System Processes. For information about the show utilization command, see Managing Modules.

Note: When you issue the show utilization command, the system releases available memory on the SRP module immediately; however, the display appears a few seconds later.
