[CentOS] Trouble brewing in dmesg... any ideas?

Ugh yes... I forgot that everything is logged to /var/log/messages. I've put a complete log from boot to current at: http://208.79.71.67/temp/messages.full.txt . I've removed the thousands of lines generated by snmpd telling me about my monitoring system connections and sanitized any other 'sensitive' information. Looking at the log, I see that I installed snmp(with libs and utils) and lm_sensors right before the problem started happening. I'm also not sure if it makes a difference but this box has 4GB of RAM and I'm not using a PAE kernel. I appreciate any help you all can lend. Thanks!!!

dmesg > dmesg.log 

or 

cd /var/log/ 
ls -lat | more 

i liked the old days when dmesg, /var/log/messages and other syslog stuff was displayed automatically on a tty console. I tried a softlink from /var/log/messages to tty9, but didn't have any luck. Would it require a tee or a mod to dmesg?

Unfortunately I can't see the top of the errors as there are too many... :-( I'll throw a console on it and start logging. Is anyone else seeing this sort of activity? I'm running the latest stock kernel available using yum from the repos. I'm not using any additional repos(rpmforge, epel, etc...) and I don't have any custom compiled modules. This box is a fresh installation running bind, apache, and mysqld.

Would need to see the full error but it sounds like a kernel oops. For 
me at least the useful info would be at the top of the error which wasn't 
included in your email. 

Worst case, configure your system with a serial console and capture the 
error using a terminal emulator on another machine plugged into your 
serial console.
