host xx.xx.xx.xx/ifx ignores redirects for xx.xx.xx.xx to xx.xx.xx.xx

Hello,

I have a multihomed gateway machine that also acts as a router.  Every once
in a while I get the message

host xx.xx.xx.xx/ifx ignores redirects for xx.xx.xx.xx to xx.xx.xx.xx

on the screen and in the log files.  I did a Google search and really didn't
find much as to:

why its happening?
how to make it stop?
is something configured wrong?

Here are the kernel configurations

net.ipv4.ip_forward = 1
net.ipv4.tcp_syncookies = 1
net.ipv4.ip_always_defrag = 1
net.ipv4.icmp_echo_ignore_broadcasts = 1
net.ipv4.icmp_ignore_bogus_error_responses = 1
net.ipv4.conf.all.rp_filter = 1
net.ipv4.conf.all.accept_redirects = 0
net.ipv4.conf.all.send_redirects = 0
net.ipv4.conf.all.accept_source_route = 0
net.ipv4.conf.all.log_martians = 1

If there is any other info I can provide please feel free to ask.

Thanks,
Danny L. Morgan
