After looking at the man page, and understanding all of ~35% of it, I'll ask this: Are you referring to the oft-mentioned, ill-configured, INET6 records in some DNS servers, or are you referring to less-than-correct code in FreeBSD's TCP/IP stack, or are NSPR's routines indeed flawed? I guess I'll ask this, too: is getaddrinfo(3) called by gethostbyname(3)? It's the latter that Mozilla/NSPR calls, and is the blamed culprit. For giggles, I disabled INET6 in the kernel, re- built and installed it, and the problem vanished. But this doesn't answer the question: Is it problematic DNS records, a problematic OS, or what? The second, I doubt... > Cheers, > Matthew Thanks, Dave -- Windows: "Where do you want to go today?" Linux: "Where do you want to go tomorrow?" FreeBSD: "Are you guys coming, or what?"
