Thats a good clue. Perhaps your shared memory segment is not big enough or
the kernel failed to allocate such a big memory segment.
Play with SHMMAXPGS options...
>From LINT:
options "SHMMAX=(SHMMAXPGS*PAGE_SIZE+1)"
options SHMMAXPGS=1025
The other possibility is that your login defaults are too small:
{hasty} limits
Resource limits (current):
cputime infinity secs
filesize infinity kb
datasize 524288 kb
stacksize 65536 kb
coredumpsize infinity kb
memoryuse-cur 32768 kb
memorylocked infinity kb
maxprocesses-cur 64
openfiles 1000
your /etc/login.conf dictates your limits.
And why you didn't report this earlier??
