on sunos 4, to get shared memory segments >1048576 bytes you need to
reconfigure your kernel with an increased value for SHMMAX. you ought
to be able to change it by (e.g.) dorking SHMSIZE in sys/shm.h or by
redefining SHMMAX in conf.common/conf.c. read your kernel config doc
before doing anything.
in solaris it's a bit easier, you just tweak a file in /etc..
