Matthew, It seems you contribute to a patch for low memory system. I've applied this patch to FreeBSD 4.11 and it is a real bonus in low memory situation without swap. What do you think of a DragonFly import ? :) http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/vm/vm_pageout.c.diff?r1=1.234&r2=1.235 Fabien
