We've got high CPU issue with ISR 2911 router.
It seems the CPU usage hits high is occurring daily base, possibly during business hours.
I guess this comes from old hardware + throughput restriction.
The detail about router and others is as below.
Can you advise me any clue that possibly could cause this issue?
