Seeing this issue today with a spoke in India. We have dual hub dual cloud and if either tunnel is up the CPU spikes to 99% and the router starts dropping packets. If I shut both tunnels down everything returns to normal and I have no idea what could be causing it? Something pushing a lot of data across the DMVPN tunnels? Once I bring the tunnels backup I see EIGRP constantly flapping and the CPU spikes immediately but nothing showing me what is causing the problem. If it is someone trying to push traffic between sites it would show regardless of which tunnel was up as they are redundant but I am at a loss.
No changes made to this router. Any ideas?
