My MBP has

kern.sysv.shmall: 8192
kern.sysv.shmseg: 8
kern.sysv.shmmni: 32
kern.sysv.shmmin: 1
kern.sysv.shmmax: 33554432

I think you possibly have the meaning/units for shmall and shmmax
reversed.  shmall is in pages, shmmax is in bytes.  I wouldn't be
surprised if the shmall value you're trying to stuff in there is
overflowing to zero...
