how to start ASE?

I reboot ASE 12.5 on CentOS by reboot command.

After that, I then want to start Sybase ASE by the script like RUN_ASEServer, but got the error:

....

00:00000:00000:2014/04/02 15:20:59.29 kernel os_create_region: shmget(0xf402f68e): No space left on device

00:00000:00000:2014/04/02 15:20:59.29 kernel kbcreate: couldn't create kernel region.

00:00000:00000:2014/04/02 15:20:59.29 kernel kistartup: could not create shared memory

Not sure why.

How to resolve it?
