 From the AIPS Manager FAQ page:

  On the latest "leopard" systems, /etc/rc is gone and creating it will 
have no effect. 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.
