No, I've only dealt with 10.4. From what I've read Apple changes shm configuration methods every couple 10.X or so. Older versions, such as 10.2, used other files. But for 10.4 (possibly also 10.3) you have to place the configuration for shmmax, shmmin, shmmni, shmseg, and shmall in /etc/sysctl.conf or somewhere in the boot scripts before OS X sets them. -- Seneca tentra@xxxxxxxxx
