So, something doesn't add up here: During a high CPU event, this is the output of show processes cpu:

This is the output of show cpu: show cpu 99 percent busy, from 289 sec ago 1 sec avg: 99 percent busy 5 sec avg: 99 percent busy 60 sec avg: 99 percent busy 300 sec avg: 99 percent busy It's 99% busy and the control plane is barely responding. Any thoughts on a hidden process that may be monopolizing the system?
