A single 100Mbps half duplex ethernet link may reach as much as 150000 pps with tiny datagrams, which is far beyond 2621's forwarding perfomance and comparable to 7513's with VIP4-80, RSP8. Not to mention packets addressed to the routers, which will probably get handled by the RSP IOS on 75xx. This may be the reason for those routers dying. Of course, opinions expressed are my own and not of my company, nor Cisco Systems. I can easily be wrong on this. I'm just reading the docs.
