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.
The following sections describe the commands used to display memory usage in a router, and what to
do if a low memory warning is displayed:

show configuration failed noerror command:
