I set shmall to the same as shmmax, it didnt help


root at Issac # sysctl -a | grep -i shm
kernel.shmmax = 2198066816
kernel.shmall = 2198066816
kernel.shmmni = 4096
kernel.shm_rmid_forced = 0
vm.hugetlb_shm_group = 0


I have 8GB of ram and I'm using the following kernel:
  # uname -a
Linux Issac.consistentstate.com 3.1.5-1.fc16.i686.PAE #1 SMP Fri Dec 9
