Is the 10% load on the management module or the line card(s)? What does a "show cpu lp" give you? What about a "show cpu ave all 5"?

We have about 17 XMR4000s with 20port 1G SFP cards and don't notice any problems with ICMP toward VE interfaces regardless of number or slot location of ports. We're still running 5.1 IronWare.
