[PLUG] Troublesome linux box

I have a tower box that I use as a file server at my home.  It's doing
nfs exports to some workstations, as well as some other functions
(dns,dhcp,samba,slimp3 server).

It has been very unstable the last 6 months.

The only clue I have is some messages from dmesg.  If anyone has any
insight into some troubleshooting steps I'm really looking for some
answers.  Please see the dmesg below....

-- 
If a nation values anything more than freedom, it will lose its freedom;
and the irony of it is that if it is comfort or money it values more, it
will lose that, too.
                -- W. Somerset Maugham
