Cannot Access Semaphore Identifier
The /usr2 directory has been filling up to 100%.
This is because a log file called MSGRCV fills up with the following messages :
ERROR: cxmm600a: error occurred
message error = Cannot Set Semaphore for Exclusive Shared Memory Access (9)
system error = Identifier removed (36)
ERROR: cxmm600a: error occurred
message error = Cannot Access Semaphore Identifier (8)
system error = No such file or directory (2)
I don't really know where to start looking - does anyone have any ideas what could be causing this
Much appreciated.

Re: Cannot Access Semaphore Identifier
What to do depends on use.
It would appear you may not have enough shared memroy.
With glance gpm you can check shared memory use. If you are close to 100% consider increaseing it.
shmmax
shmseg
shmmni
With 11.00 you must set and compile a new kernel.

Re: Cannot Access Semaphore Identifier
What should I be looking at in glance?
The kernel params are set as follows :
Shmmax 536870912
shmseg 512
shmmni 768
IPCS shows the following :

Re: Cannot Access Semaphore Identifier
gpm
reports
system tables report
Shared memory usage is all over this report.
gpm/glance is a pay for add in product but it can be installed of the Core OS or application cd's for a 60 day fully functional trial.
