> You need to create an /etc/sysctl.conf file and put the values in it,
kern.sysv.shmmax=10485760
kern.sysv.shmmin=1
kern.sysv.shmmni=32
kern.sysv.shmseg=8
kern.sysv.shmall=4096
You should use the values you had when you were running tiger. Those
could be in /Previous\ System/etc/rc, assuming you have "Previous
System". So three different OS upgrades and three different ways to
adjust the default shared memory. Note: You will need to reboot the
system for the change in shared memory to take place. You can check if
the shared memory changes happened by typing "sysctl kern.sysv" in a
terminal or xterm window. Look for the kern.sysv.shm* values. If the
values have not changed, make sure you haven't inadvertently left in
"sysctl -w" in the /etc/sysctl.conf file or mis-typed one of the values.
If the /etc/sysctl.conf file is not properly formatted, or shmmax is not
an integer multiple of shmall, the shared memory will not be adjusted
after the reboot.
