Weird Kernel Messages in /var/log/messages

Hi there,
    I have recently upgraded to RH6.0 on a PIII 550 MHz machine.  The
system was running fine until I put some users on it (and caused
somewhat of a load).  I now frequently get messages similar to:

    After getting these messages, the machine will crash or go into an
unusable state.  Last night, it appeared to effect the password
verification procedure and I ended up with many messages like this:

    I have read in other posts that the kernel messages are happening to
others as well.  Has anyone found a suitable fix for them?  Is it driver
related.  Other posts suggest that it is corrupted RAM, some suggest
driver problems and to upgrade the kernel.  Other posts suggest hardware
and kernel upgrades to not help and one post suggests that it is related
to the APM functions of some BIOS.  I have disabled the APM in bios and
still have the weird kernel messages in /var/log/messages.  It is
becoming really annoying to have to babysit this brand new machine.  Any
suggestions greatly appreciated.  Thanks in advance.

If you think that it is a software (kernel) problem, then you should
try your system with the newest stable kernel (2.2.13), and if that
does not help, report a bug.  There are helpful suggestions in the
REPORTING-BUGS file in the kernel source.

1. Weird messages in /var/log/messages

Hello every1,

I have a good working FreeBSD 4.0-release natd/firewall machine. But in my
/var/log/messages 2 lines just keep showing up:

This is very irritating and i have no idea how to solve this. The ipaddress
13.10.15.10 is unknown to me and i have no idea why it's trying to arp it.
The other message probably has something to do with some kind of
misconfiguration. But as far as I can see everything's just fine.

Some output information of ifconfig which might be useful:

fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 192.168.0.1 netmask 0xffffff00 broadcast 192.168.0.255
        ether 00:c0:0d:01:08:2f
        media: autoselect (100baseTX) status: active
        supported media: autoselect 100baseTX <full-duplex> 100baseTX
10baseT/UTP <full-duplex> 10baseT/UTP
ep0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 24.132.7.(private:)) netmask 0xfffffe00 broadcast 24.132.7.255
        ether 00:20:af:5d:f0:2b
        media: 10baseT/UTP
        supported media: 10baseT/UTP
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
        inet 127.0.0.1 netmask 0xff000000

Output of arp -a:

h6rtr1.a2000.nl (24.132.6.1) at 0:10:54:58:24:8 [ethernet]

Some relevant information out of my /etc/rc.conf:

gateway_enable="YES"
firewall_enable="YES"
firewall_type="open"
network_interfaces="fxp0 lo0 ep0"
ifconfig_fxp0="inet 192.168.0.1 netmask 255.255.255.0"
ifconfig_ep0="inet 24.132.7.(private:)) netmask 255.255.254.0"
ifconfig_lo0="inet 127.0.0.1"
natd_enable="YES"
natd_interface="ep0"
defaultrouter="24.132.6.1"

Does anyone recognize this problem and/or knows how to fix this?

Thanx very much in advance!
