You're probably running into the kernel limit on the maximum size
of a shared memory region.  To get started, try giving -N and -B
switches smaller than the default values (-N 8 -B 32 should work
unless your kernel SHMEMMAX setting is real small).

In the long run you'll probably want to increase your SHMEMMAX
setting so that you can run with more buffers, but I don't know
where to set that on SCO.
