I have a 3845 that I use as a BGP and Eigrp router. As of recently, I have been getting spikes of high CPU utilization. The top process is the 'Per-Second jobs' process. Cisco's description does not provide the most detailed explanation of what this process does:
Performs a variety of tasks every second; executes registered one_second jobs
Is there more detail on what his process does in specific? Or even better, are there some debugs I could run that would more specifically show what is causing the CPU utilization to spike? There have not been any major changes to my configuration from before this issue began. I recently turned on nbar protocol discovery, but that is about the only recent feature change on the box. Any help would be greatly appreciated.
