Actually, SHMMAXPGS * 4096 == kern.ipc.shmmax so if you set SHMMAXPGS to some value, you need to multiply that by 4096 to set shmmax. I think the kernel should warn you if you set SHMMAX > SHMALL. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Vivek Khera, Ph.D. Khera Communications, Inc.
