I don't recall finding "a solution" per se; that said, I also don't recall seeing an occurrence of the above for enough time that I'm not sure when I sent that message. :-} As a reality check: g1-252(11.0-C) ls -lT /*.core -rw-r--r-- 1 root wheel 13783040 Aug 18 04:19:03 2015 /ntpd.core g1-252(11.0-C) So -- among other points -- my last sighting of whatever was causing that was the day I built: FreeBSD 11.0-CURRENT #157 r286880M/286880:1100079: Tue Aug 18 04:45:25 PDT 2015 r...@g1-252.catwhisker.org:/common/S4/obj/usr/src/sys/CANARY amd64 Note that the machines where I run head get updated daily (unless there's enough of a problem with head that I can't build it or can't boot it (and I'm unable to circumvent the issue within a reasonable time)) -- and while I do attempt to run ntpd on the machines, the above failure is more "annoying" than "crippling" in my particular case. And I'm presently running: FreeBSD 11.0-CURRENT #227 r290138M/290138:1100084: Thu Oct 29 05:12:58 PDT 2015 r...@g1-252.catwhisker.org:/common/S4/obj/usr/src/sys/CANARY amd64 and building head @r290190 as I type. And FWIW, I *suspect* that one of the issues involved (in my case) was a ... lack of determinism ... in events involving getting the (wireless) network connectivity into a usable state as part of the initial transition to multi-user mode. (I only have evidence at the moment of the issue on my laptop; my build machine, which only uses a wired NIC, has no /ntpd.core file. It and my laptop are updated pretty much in lock-step; it runs a completely GENERIC kernel, while the laptop runs a modestly customized one based on GENERIC.) Peace, david -- David H. Wolfskill da...@catwhisker.org Those who would murder in the name of God or prophet are blasphemous cowards. See http://www.catwhisker.org/~david/publickey.gpg for my public key.
