kernel meltdown

[Anna Riley]

Hi there,
	I am hoping someone can help me.  This morning one of our web servers crapped itself and I don't know why.  It's running RedHat 7.2 kernel version 2.4.9-31smp.  I couldn't login from the console so I had to reset it.  When it came back up it was fine.  This is what I am seeing in the messages log:

I have searched on google for some of these messages but I couldn't find anything helpful.  Any help or direction would be apprecaited. 

I am not subscribed to this list so email to me directly would be great.  If I am mailing to the wrong list my apologies.

Thanks so much all!
