My system turned into a swap loop with no change in the amount of free memory and no 128k area free. Probably this is because there's not one single 128k area without an unswappable page in it. The only way I see around this is to disallow kernel memory allocation and locked pages in a certain part of physical memory, but maybe there's another way... grtz, Rik. +-------------------------------------------+--------------------------+ | Linux: - LinuxHQ MM-patches page | Scouting webmaster | | - kswapd ask-him & complain-to guy | Vries cubscout leader | | http://www.fys.ruu.nl/~riel/ | | +-------------------------------------------+--------------------------+
