Hi everyone,
A customer reported that their router experienced spikes (high cpu utilization) every 4 hours and claims that it is caused by snmp polling of the Ciscoworks server
The process SNMP engine is the process that causes these spikes .We think that the job responsible of this periodic high CPU utilization. It's called "Vrf Collector Job" and it's runnning every 4 hours.
Below the result of show stack PID and show version
