Hi,

This looks like you are hitting bug CSCur17744 or similar.

High CPU increases when enabling flexible netflow under the interface and subinterface level.
There is No work-a-round

May be try IOS c2951-universalk9-mz.SPA.156-3.M9.bin

I have already downloaded c2951-universalk9-mz.SPA.157-3.M6.bin on flash:

but i want to make shure before upgrade that is an IOS issue. BTW i will replace 2951 to 4351. and will play aroung with 2951^)
