We really need to see what gets logged to /var/log/messages before the 
crash, but I'll hazard a guess that a) you've got a buggy kernel that's 
croaking under load b) you've got way too little memory and the system is 
just /very/ slow from swapping or c) you've got broken hardware; most 
likely RAM, disc, or memory controller in that order.

If you suspect c) run memtest+ or memtest86 on the system for a day or so 
and see if any faults are logged.

Best Regards,
Alex.
