ipcs -sa and semaphores

[KPS]

We're looking at ipcs -sa output and we're trying to determine something we're seeing with regard to info in the OTIME column of the attached output. In a lot of cases, we see "no-entry" under the OTIME column and we're curious to know what this implies?

We're worried this might mean that the process grabbed semaphores, but never let go of them when the process run completed.

Could someone clarify for us what this is telling us?

Thanks,

This means the semaphore was created but never used.
