OK; got another one. This time, I have the complete /var/log/messages for a verbose boot, from that boot to just a bit after the ntpd crash; it's in <http://www.catwhisker.org/~david/FreeBSD/head>; as of the moment, that contains: [PARENTDIR] Parent Directory - [ ] CANARY 2015-03-22 10:03 15K [ ] CANARY.gz 2015-03-22 10:03 6.3K [ ] ntpd.core 2015-07-24 05:31 13M [ ] ntpd.core.gz 2015-07-24 05:31 124K [TXT] ntpd_crash_msgs.txt 2015-07-24 05:40 138K [ ] ntpd_crash_msgs.txt.gz 2015-07-24 05:40 19K This was running: FreeBSD g1-245.catwhisker.org 11.0-CURRENT FreeBSD 11.0-CURRENT #133 r285836M/285836:1100077: Fri Jul 24 05:24:41 PDT 2015 r...@g1-245.catwhisker.org:/common/S4/obj/usr/src/sys/CANARY amd64 Trying "gdb /usr/obj/usr/src/usr.sbin/ntp/ntpd/ntpd ntpd.core" still doesn't help much: This GDB was configured as "amd64-marcel-freebsd"...(no debugging symbols found)...

(gdb) I am presently suspecting that it's a bit dependent on ... well, "timing". I have my ~/.xsession set up so that once I've entered the passphrase(s) for my SSH private key(s), scripts start running to establish connections to other machines -- e.g., open an xterm locally, ssh over to my mailhub and (re-)establish a tmux session on that machine where I run mutt to read & write email (such as this message). While that almost always Just Works in stable/10, it's rather ... spottier ... in head -- I'd say it's about a 50% probability that it will work, vs. the ssh connection attempt hanging, and eventually timing out. But if I've waited (say) 30 seconds or so, I can establish such a connection easily. Granted, I am using wireless (802.11), but I get a sense that "things" are claimed to be "ready to go" a bit prematurely -- at least sometimes. Peace, david -- David H.
