 Can you verify that it's actually nmap that is either not sending all
 the ICMP Echo Requests you'd expect, or not correctly registering all
 returning ICMP Echo Replies, using tcpdump on all the involved boxes?
 
 Also, please compare what you see on the wire with what nmap claims to
 be doing (enable verbose mode and packet tracing).
