address being mapped was 32786. So why was I having trouble ? Turns out that the value of dac_mmap_min_addr can be set by sysctl "/proc/sys/vm/mmap_min_addr". Doing a
cat of this file showed it was set to 65536 ! Bingo ! I then did
# sysctl -w vm.mmap_min_addr=32768
I hope you didn't install one of my kernels, otherwise I'd have to say shame on you for not reading the README-22.214.171.124. It tells you to do exactly that. It's in all of the README's going back to 2.6.30-rc6.
