CCR1036-12G-4S sudden High CPU Utilization

Hello All,
we have removed all the traffic policies after which the CPU utilization normalized but since last couple of days we are observing the WAN traffic gets drop briefly, upon investigation we found that CPU utilization is high during traffic degradation time. This happens for short period of time few seconds though.

Why the router CPU is jumping now we have only PPPoE users on the router without any CPU intensive traffic policing or additional queues.

Anyone else encountered this issue?

Thanks
Faisal.

I don’t know if this is the case - but mass PPPoE disconnections are known to tax the CPU of the CCRs. Have You checked it?

1200 PPPoE users only.
