Ok, thanks. I got that impression from reading some posts I found while googling. There was one in particular for NetBSD that discussed it in detail. Check out the Apr 2 portion of this http://www.tinyurl.com/b46gq by Jan Schaumann. Also this one http://tinyurl.com/9sa6a. From these posts it appears that SO_REUSEPORT is needed in some cases to be compatible with linux. -Kurt
