    Is /dev/shm large enough (if you have memory_target set)?

    

    Cheers,

Is this a new installation or has it
            worked before?  

            

            First guess is that you do not have the shared memory and
            semaphores configured - should be in /etc/sysctl.conf

I am getting the following error on RHEL

Any idea what the issue is?
