[clug] Oops Question

As some may remember, I have had a slightly unreliable server for 
awhile.  It has been nicely stable for the last couple of months since I 
swapped out the CPU and PSU - at least until today.

Today I got an oops - and one I was able to keep a log of courtesy of 
the syslog (yippeee!!!).  If I understand the oops correctly, it 
'faulted' in a cat process which makes sense as I was running a script 
which included a number of cat commands on /proc to get some temperature 
readings.  However, the oops traceback seems to indicate it was in ipv4 
networking code as well as proc reading.

So, is the basic problem in the lm-sensor modules/code?  Running a 
Debian 3.0 system with Adrian Bunks 2.4.21-5-686 kernel with the 
standard Debian lm-sensors-source (2.6.3-5) compiled up into a custom 
package. (Yes I know Adrian has released 2.4.23 of the kernel and will 
be upgrading to it soon.)  System was not doing much else besides 
running SETI at Home which I had only started up again yesterday. 
Coincidence? Samba, squid, apache, fetchmail, newsplex, dhcpd, pdnsd, 
mysql also run on this system but were basically sleeping ie doing nothing.

System details is an Abit BE6-II, PIII 550MHz, 320M RAM, 1 Seagate 40G, 
1 Fujitsu 8G, CD, Ricoh CD Burner, AEC6712S SCSI, Realtek NIC.

Oops text is attached. Any help/advice would be appreciated.  I have a 
feeling that this box is going to have to be replaced soon, just want to 
delay it for as long as possible....
