Thanks to Joerg Bruehe and Gavin Kreuiter

sem-mni is maximum number of semaphore identifiers.
sem-msl is maximum number of semaphores per identifier.

Therefore, sem-mni X sem-msl = total number of semaphores, so maximum for my
case is as follows:

        sem-mni = 1024
        sem-msl = 50

        1024 X 50 = 51200



We are running Tru64 UNIX v4.0F and sem-mni = 1024. The system is currently
running with 510 semaphore sets allocated and 1570 semaphores.

Q: Does having move semaphores allocated than allowed (by sem-mni) cause
problems? How much can you exceed max?
