The essential message
    shared memory ID failure
is present in your output.

Therefore

  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.

To quote from the aips manager FAQ.
