This behavior has been replicated under two different 2.2.1-RELEASE machines. Here are the relevant readouts from icmplog: Apr 11 01:40:22 carthage icmplog: Echo Request from 207.171.204.72 Apr 11 01:40:26 carthage last message repeated 4 times This was the result of a 'ping -c 5 207.171.204.72' command.
