This plugin runs the standard ping program, right? If you ping the same
host with two ping commands at the same time, both will report duplicate
packets, because they can't distinguish between each others' pings.

So this problem may just be caused by someone or something pinging from
the nagios server to the remote host at the same time as Nagios does its
checks.

Cheers, Chris.
