I ran the test program on a 2.6.21 x86_64 with 2GB and the test program doesn't make the system unusable but it fails when it runs out of free memory and has to start recycling. This is almost the same to the original problem and I wonder whether there is a missing patch somewhere or any reason why this was not fixed in newer versions. thanks
