Share Memory setting in Soalris 10 or +

(1) If it is a shared memory issue, it may not be zone specific but S10 specific. Since it
/etc/system is not good practice but following S10 resource control practices
(2) Using prctl to project or even process based control. However, you need to create
project and assign user which running the process to the project. I have experienced
some bugs before to do this assignment. However, to login as the user then su to
root to assign the project
(3) projmod -s -K "project.max-shm-memory=(privileged, 8GB, deny) xxx

You may need to run it in global zone first before moving into local zone.
