I am certainly not an expert in OSX, but many Unix variants have to have the changes made in the conf directories; then the kernel has to be rebuilt AND the environment rebuilt. It is not a one step process on all Unix variants. I don't know for sure, but rebuilding the environment after making the changes to the files in the conf directories may rebuild the rc files.

Neil,

I posted to the apple site asking if anyone could
recommend the 'correct' place to edit these settings.
I don't think a change like this would survive a
system update.....

But it was the only way I got the settings to 'take'.

It deserves to be mentioned in the docs that this is
necessary at least as far as 10.3.1 (osx).

you must edit the /etc/rc  file.

/System/Library/StartupItems/SystemTuning/SystemTuning

Should we update the documentation's advice? At
present, it suggests:

MacOS X

    Edit the file

/System/Library/StartupItems/SystemTuning/SystemTuning

and change the following values:

sysctl -w kern.sysv.shmmax
sysctl -w kern.sysv.shmmin
sysctl -w kern.sysv.shmmni
sysctl -w kern.sysv.shmseg
sysctl -w kern.sysv.shmall

(Without a Mac OSX box, I have no idea which is
correct.)
