I agree with David that it looks like the box was swapping badly before the end. You may like to look in the logs to see if the out of memory killer woke up. Linux has supported per process accounting for eons. I'd recommend enabling it so you will have good info if this ever occurs again. With per process acounting you can go back and see what commands were started when and how much they were paging (lastcomm -p). I also recommend enabling sar which gives useful systemwide performance stats.
