[ ...comments about moving to 6 snipped for brevity... ] That's OK, I wasn't soliciting advice on which platform or OS version a given set of machines ought to run. When the number of machines one deals with in a given environment changes from single-digit, to dozens, to hundreds, to tens of thousands, keeping machines updated to a bug-free, stable environment is more important than chasing features off the latest branch. As always, your mileage may vary. >> I'm starting to feel thankful that my important domains include >> off-site secondaries which are running djbdns. > > EGRATUITOUSBINDBASHING You seem to be disposed to believe it so, but regardless of opinions, I've had named crash under moderate loads and it concerns me enough to evaluate switching to a heterogenous nameserver environment to gain more stability from a critical service. If I wanted to indulge in gratuitous bashing of BIND, I wouldn't do so on a FreeBSD mailing list, nor would I make an effort to be tactful even when it seems that a bug report or any criticism (direct or implied) would be misinterpreted as "gratuitous bashing" regardless of whether it concerns a legitimate problem. >> Does the FreeBSD security team have a position with regard to whether >> the above DoS vulnerabilities ought to be fixed in the 5-STABLE branch? > > They are actually reviewing the issue as we speak.
