System crash

[Christopher Delfs]

I have a dual processor box used for calculations that has run tirelessly for 
three or four years.
In september last year I installed from scratch RH-7.1  and again this 
computer kept working tirelessly.  Then a few weeks ago I had a system crash.
Apart from the error occuring in kswapd (kernel swap daemon?) I can't see 
much else.

Any suggestions?

Oop I meant to include this
