I had a simular issue and i received these comments .
High CPU Utiliazation is normal on VIP.
Check out the file, Internetworking Troubleshooting Handbook, Second

Sorry I do not have a link
The fix was to issue no ip route-cache on each serial interface.

Hi Vishal,
Can you try disabling the " ip accounting" feature for a while and
see if
its enabled?
Regards,
Subhash.
