Take a look at /usr/src/sys/sys/sem.h. I did a grep for SEM and found: sem.h:#ifndef SEMMNI sem.h:#define SEMMNI 10 /* # of semaphore identifiers */ sem.h:#ifndef SEMMNS sem.h:#define SEMMNS 60 /* # of semaphores in system */ sem.h:#ifndef SEMUME sem.h:#define SEMUME 10 /* max # of undo entries per process */ sem.h:#ifndef SEMMNU sem.h:#define SEMMNU 30 /* # of undo structures in system */ sem.h:#ifndef SEMMAP sem.h:#define SEMMAP 30 /* # of entries in semaphore map */ sem.h:#ifndef SEMMSL sem.h:#define SEMMSL SEMMNS /* max # of semaphores per id */ sem.h:#ifndef SEMOPM sem.h:#define SEMOPM 100 /* max # of operations per semop call */ As an example of what to put in a kernel config file, the next line is in mine: options "SEMMNI=20" > > I've searched the CD-ROM FAQs but there aren't any > pointers. > > > Thanks, > Mike > <mike@networx.ie> > > > ============================================================================ Chuck Robey chuckr@eng.umd.edu -- I run FreeBSD on n3lxx and Journey2 --------------------------------------------------------------------------- The Dilbert Zone is Dilbert's new WWW home!
