On a Cisco 12000 series Internet router that is configured with an Engine 4 line card that has
256 MB of CPU memory, the show processes memory command may show more than 4 GB of used
memory. When the counter reaches 4.2 GB, it may reset to 0, which causes the line card to think it
has run out of memory and to disable Cisco Express Forwarding (CEF). Issuing the clear cef
linecard [slot-number] command will bring the line card back up. There is no workaround for the
memory problem or to prevent the counter from resetting to 0.

When IP Cisco Express Forwarding (CEF) is enabled on a Route Switch Module (RSM) and you
reload the RSM, the interfaces show that the no ip route-cache cef interface configuration command
is enabled, which causes the CPU to run at 99 percent.
