SysOrb (http://www.sysorb.com/) doesn't work without it AFAIK. IIRC, X had trouble in the past without it. Anything that uses SysV shared memory, SysV message passing (msgget(), msgsnd() etc..), SysV semaphores (semget() etc), will have trouble. In general, System V IPC is just used by many different programs... Perhaps not any you run, but it is pretty widely used. -- Jesper Juhl Don't top-post http://www.catb.org/~esr/jargon/html/T/top-post.html Plain text mails only, please http://www.expita.com/nomime.html
