It's those dang Nachi-sized ICMP echo/echo-replies. We block those at all our transit points and dial-up ports. Nachi was killing our cisco access-servers until we did this to stop the spread.

Unfortunately, this breaks Windows tracert as it uses 92-byte echo requests. Use a "real" traceroute, and you won't see this problem.
