PI 1.2 High cpu on devices when snmp poll

Question

        Hi all,
I´m setting up our new PI 1.2. After we discovered devices and successfully added, PI started to hit CPU devices every 10 minutes, when SNMP poll runs.
CPU utilization for five seconds: 99%/11%; one minute: 29%; five minutes: 17%
PID Runtime(ms)     Invoked      uSecs   5Sec   1Min   5Min TTY Process
272    23536856     1524766      15436 86.62% 17.07%  5.06%   0 SNMP ENGINE  
Is there any custom field to prevent this kind of snmp abuse on our devices?
If you need any further information, please let me know.
Regards

I will look for a router with IOS 12.something and I will perform some test. But for me, It´s something related to IP or routing table mib.
I´ll keep you aware.
