*sigh* You didn't describe the machine you're working on at all,
niether hardware (RAM available) nor OS version (of course).
The solution is to increase the amount of shared memory available
to processes.
You'll want to bump up the sysctls:
kern.ipc.shmmax: 4194304
kern.ipc.shmmin: 1
kern.ipc.shmseg: 64
kern.ipc.shmall: 1024
These are also documented in the most recent copies of the
GENERIC kernel config file.
