Great.
I checked my Solaris box using sysdef and got:
* IPC Semaphores
* 10 entries in semaphore map (SEMMAP) 10 semaphore identifiers (SEMMNI) 60 semaphores in system (SEMMNS) 30
undo structures in system (SEMMNU) 25 max semaphores per id (SEMMSL) 10 max operations per semop call (SEMOPM)
10 max undo entries per process (SEMUME)32767 semaphore maximum value (SEMVMX)16384 adjust on exit max value
(SEMAEM)
There are so many tunable paramters! I expect cleaner explanations for
these kernel variables from Marc's document.
