It just didn't. It's a shame. An interesting question. I had always thought that SMP was (one of?) the technical reasons why Sun moved from a BSD to a System V base. Since then, of course, we've done lots of work on SMP support for at least FreeBSD. Does anybody have an overview of how good the support is compared to modern Solaris? Is there any intrinsic reason why one should be better than the other? Greg -- Sent from my desktop computer. Finger grog@lemis.com for PGP public key.
