Ok

So i have a wierd thing going on. Has anyone else had a similar issue
or at least maybe an idea of what may be occuring.

I have a 7206vxr that was running 12.2(24a) connected to a 3660 running
12.2(10d).
     This 3660 is doing a lot of NAT, the CPU of the 3600 is less than
30%

I upgraded the 7206 to 12.3(12b) over the weekend and the remote side
routers, which all run 12.2(10d), all started to have CPU utilizations
up near 100%.

If I move the remote side router to a different ditribution router that
does not run 12.3 the CPU goes back down to less than 30%

Thanks
