Thanks Terry.
On Tiger, is there a way to clean up System V semaphores that may have
been left behind by processes that have gone away, possibly by writing
code?
Thanks,
Ray

I seem to be unable to get a list of currently existing System V

empty, whether or not I run the command as root. On Leopard,
however, ipcs works as expected.
Is this a known issue, or is there something I'm missing?
The kernel support for the ipcs code and the structure changes
necessary in the contract between kernel and user space was
considered to risky to put in Tiger, so Tiger does not support it.
