according to /usr/src/linux/include/linux/shm.h:

#define SHMALL (SHMMAX/PAGE_SIZE*(SHMMNI/16)) /* max shm system wide (pages)
*/

On my machine here, it is 2097152. It should be the same on any Intel IA32
compatible machine. To be safe, remove the value from /etc/sysctl.conf and
reboot the machine ;-).
