you're not accidentally using shmfs or tmpfs are you ?
(or otherwise have a leak in sysv shm)


you can use the "ipcs" command to see your shm allocation

(and for tmpfs/shmfs... check if you have it mounted anywhere.
Something like /dev being on shmfs and /dev/null being a file not a
device can.. totally screw you over)
