E=28 semget(20038,1,2047) (28: No space left on device) on Solaris 10

Question

We are running 5 SAP ECC 6.0 systems on Solaris 10 with the project definitions configured as mentioned in note 724713.
Now after the fifth system was installed, we have problems to start all of the systems.
The error can occur for either of the systems and in dev_disp it would say:
ERROR => e=28 semget(20038,1,2047) (28: No space left on device) [semux.c      928]
ERROR => CCMS: SemInit failed  [alxxappl.c   610]
ERROR => CCMS: sAlInit: could not create/attach shared memory key 13 (rtc = 255) [alxx.c       1187]
Before the fifth system was installed, we didn't experience any problems.
Do we have to change the project definitions and if yes how?
We have defined 5 projects (each system) with the following values for each project:
SD2:200:SAP System SD2:orasd2,sd2adm::process.max-sem-nsems=(priv,2048,deny);project.max-sem-ids=(priv,1024,deny);project.max-shm-ids=(priv,256,deny);project.max-shm-memory=(priv,18446744073709551615,deny)

Answer 1

I have changed the project vith projmod it looks now like :
htudv# projects -l `projects -d sd2adm`
SD2
        projid : 200
        comment: "SAP System SD2"
        users  : orasd2
                 sd2adm
        groups : (none)
        attribs: process.max-sem-nsems=(priv,2048,deny)
                 project.max-sem-ids=(priv,1024,deny)
                 project.max-shm-ids=(priv,1024,deny)
                 project.max-shm-memory=(priv,18446744073709551615,deny)
htudv#
But when I start SD2 I still get:
ERROR => e=28 semget(20038,1,2047) (28: No space left on device) [semux.c      928]
ERROR => CCMS: SemInit failed  [alxxappl.c   610]
And what confuses me is that all the processes started under sd2adm I watched with
prctl -t privileged <pid> , have a value like
project.max-shm-ids
        privileged        128       -   deny   ???
Why not 1024 as defined in the project?
