Type 'uname -a' and see if it mentions SMP at all. Also, how much swap space do you have, and what does 'cat /proc/meminfo' tell you? With 256M of RAM, if you are running X, and practically anything else, it wouldn't surprise me that it's complaining about being out of memory. Of course, if you aren't using X, or really much of anything else, there might be a bug in your compile.
