I am running Red Hat 6.2 behind a firewall on a private 10.12.50.x network.
I have been getting these strange ICMP broadcast errors that occur every 12
minutes constantly. I don't not have any machine with the address 10.0.0.1
I can trace them back to a specific day and time when they started, but I
was not doing any work on the kernel on that day or anytime around that day.
Here is the output of /var/log/messages
Note: the "..." represent normal output between ICMP errors
Jul 5 00:20:36 linux1 kernel: 10.0.0.1 sent an invalid ICMP error to a
broadcast.

Any help or insight would be greatly appreciated.
