Memory Warnings in Configuration Sessions
The Cisco IOS XR software automatically monitors and manages the system resources in a router.
Under normal operating conditions, memory problems should not occur.
When a low-memory issue does occur, it is often in the form of a low-memory warning during a
configuration session. Low-memory conditions can be caused by multiple, large configurations being
added to the router at a single time. Users can remove the source of a problem by removing
configurations.
