If still not fixed based on above input; check if there's a broadcast or multicast storm which could be affecting your dynamic routing - can be fixed using storm-control broadcast/multicast level command on a per interface level or globally (depends on platform). You can also set some control-plane limits to help limit CPU resource utilization. Kennedy On Tue, Oct 2, 2018 at 1:09 PM Thuo Wilson via skunkworks < skunkworks@lists.my.co.ke> wrote:
Check ACL, Route maps, NAT overload or flood attack - those are main culplits. Also check dynamic route looping - like OSPF - big consumer. Kind Regards, Wilson./

More details.
While digging, I have disabled snmp-server and some debug logging configs. Now I have:
C1841#sh processes cpu sorted CPU utilization for five seconds: 64%/17%; one minute: 78%; five minutes: 66% PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process * 121 467636 134723 3471 45.27% 55.87% 47.09% 0 IP Input*
I still think this is high, no? I need to figure out what exactly comprises IP Input
