I have the same problem with smokeping and fping. I'm running Redhat 7.1 
with a 2.4.2 kernel and fping 2.4.2_to. 

Once the ping to the site fails fping can't ping the site anymore. I fping
the site outside of smokeping and it will also fail. Ping works fine.
I used tcpdump to check the network traffic on the computer and it shows
the ping request packets. However a sniffer monitoring the router ethernet
port doesn't see the packets.

I don't know enough about the Linux network stack to point my finger at a
specific section of the code. It is very interesting that the packet is 
visible to tcpdump but doesn't seem to make the wire.
