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??
