It's due to certain systems with misconfigured TCP/IP stacks. If you
want to get rid of it,
'echo 1 > /proc/sys/net/ipv4/icmp_ignore_bogus_error_responses', and put
this somewhere in your startup scripts to cause it to be set each time
you boot.

Alternatively, instead of fiddling with your startup scripts, you could
install the systune package and put the following line in
/etc/systune.conf:

  /proc/sys/net/ipv4/icmp_ignore_bogus_error_responses:1
