[c-nsp] Troubleshooting High CPU

[Eninja]

What platform is the device? Are the primary and standby devices the  
same - platform, SW, config, traffic?

During the spike, is the CPU consumed at interrupt or process level?

Grab and send over sh proc cpu, sh align, sh int stat, sh log (if  
device is too unresponsive during failover, have onsite personnel pull  
out traffic-laden cables one by one until device is responsive, grab  
captures before reinserting cable/s).

-Eninja
PS. Disable console logging
