You can use 'show processes cpu' to see what process is consuming cpu. The
process 'IP input' indicate how many ip traffic you have.
The problem may be the router or something (traffic) entering the router.
You can try isolate the source of the problem by shutting down the
interfaces one by one. If you have more than one interface to same location
shutdown all interfaces at same time.
If you shutdown one interface and the problem stops, the problem is coming
from that interface.
One possibility is an attack from the internet, I have already seen this.
