[c-nsp] 7206VXR NPE-G1 Upgrade from 12.4 to 15.0 High CPU

[Chris Gotstein]

I copied the config before i upgraded to make sure i would catch any 
config changes.  I've double, triple and quadruple checked my config for 
anything that may have changed or got added.

only logging a few acl entries which deal with spoofing our ip ranges. 
But i'm not seeing any hits from the in the log.

Then a few days/weeks/months down the road, they reboot for one reason or another (sw upgrade for example) and suddenly the change they made previously is gone and no one notices because it was made so long ago and forgotten.
