It's not the packets per second that seems to kill them, its the amount of arp cache and sessions (figure 600 packets per second, each packet to a different host...Thats a lot of sessions in 5 minutes)Curious, in that case consider null routing unused blocks, perhaps take the opportunity to improve on subnet and vlan distribution to help the null routing.
That's exactly the case. All the unused IP addresses are nullrouted and most of the traffic was destined for the nullrouted addresses. I don't think a lot of arp activity was going on.
