I'd put a sniffer on the ethernet side and check to see if there are
any hosts constantly sending to different ip address . This would cause
the router to process switch instead of fast switch or whatever. I had a
similar problem with a router which connected to an ISP and provided
internet access for a co-located site for my company. It turned out
there was some sort of virus on the PCs of a client on one of the
network segments causing the PCs to shoot out requests constantly to
different websites which over burdened the routers cpu.
