I have had this problem since the first 9.14.0 release candidate. I have a bug open with the ISC about this, but we are all struggling to reproduce out of my one instance where it crashes. Could you provide the configuration file and the workload for that server ? Also, is the host running on bare metal or is it virtualized? And what version of FreeBSD are you running? I'm having the same issue on a FreeBSD AWS EC2 instance running 12.0-p3. It is a slave/secondary server hosting ~20 domains and very light load. I'm a little hesitant at this time to provide the config file, as I'd have to do a lot of sanitizing first. Here is the log though: May 16 18:53:12 aws pkg[91493]: bind914 reinstalled: 9.14.1 -> 9.14.1 May 16 18:53:16 aws named[91533]: starting BIND 9.14.1 (Stable Release) <id:d4c1008> May 16 18:53:16 aws named[91533]: running on FreeBSD amd64 12.0-RELEASE-p3 FreeBSD 12.0-RELEASE-p3 GENERIC May 16 18:53:16 aws named[91533]: built with '--localstatedir=/var' '--disable-linux-caps' '--with-libxml2=/usr/local' '--with-readline=-L/usr/local/lib -ledit' '--with-dlopen=yes' '--with-openssl=/usr/local' '--sysconfdir=/usr/local/etc/namedb' '--with-dlz-filesystem=yes' '--disable-dnstap' '--disable-fixed-rrset' '--without-gssapi' '--with-libidn2=/usr/local' '--with-libjson=/usr/local' '--disable-largefile' '--with-lmdb=/usr/local' '--disable-native-pkcs11' '--without-python' '--disable-querytrace' 'STD_CDEFINES=-DDIG_SIGCHASE=1' '--enable-tcp-fastopen' '--with-tuning=default' '--disable-symtable' '--prefix=/usr/local' '--mandir=/usr/local/man' '--infodir=/usr/local/share/info/' '--build=amd64-portbld-freebsd12.0' 'build_alias=amd64-portbld-freebsd12.0' 'CC=cc' 'CFLAGS=-O2 -pipe -DLIBICONV_PLUG -fstack-protector-strong -isystem /usr/local/include -fno-strict-aliasing ' 'LDFLAGS= -Wl,-rpath,/usr/local/lib -fstack-protector-strong ' 'LIBS=-L/usr/local/lib' 'CPPFLAGS=-DLIBICONV_PLUG -isystem /usr/local/include' 'CPP=cpp' May 16 18:53:16 aws named[91533]: running as: named -u bind -c /usr/local/etc/namedb/named.conf May 16 18:53:16 aws named[91533]: compiled by CLANG 4.2.1 Compatible FreeBSD Clang 6.0.1 (tags/RELEASE_601/final 335540) May 16 18:53:16 aws named[91533]: compiled with OpenSSL version: LibreSSL 2.9.1 May 16 18:53:16 aws named[91533]: linked to OpenSSL version: LibreSSL 2.9.1 May 16 18:53:16 aws named[91533]: compiled with libxml2 version: 2.9.8 May 16 18:53:16 aws named[91533]: linked to libxml2 version: 20908 May 16 18:53:16 aws named[91533]: compiled with libjson-c version: 0.13.1 May 16 18:53:16 aws named[91533]: linked to libjson-c version: 0.13.1 May 16 18:53:16 aws named[91533]: compiled with zlib version: 1.2.11 May 16 18:53:16 aws named[91533]: linked to zlib version: 1.2.11 May 16 18:53:16 aws named[91533]: ---------------------------------------------------- May 16 18:53:16 aws named[91533]: BIND 9 is maintained by Internet Systems Consortium, May 16 18:53:16 aws named[91533]: Inc.

As for the config file, you could open a bug report on the ISC's bug tracker https://gitlab.isc.org/isc-projects/bind9/issues/ and ask it to be made confidential. Or you could join the https://gitlab.isc.org/isc-projects/bind9/issues/943 issue, that is also confidential. (But I am unsure on how to add you there.) If I keep trying to start the daemon, it eventually doesn't crash. I registered at ISC's GitLab as wcarson, but I'm unable to see the existing issue. (In reply to Mathieu Arnold from comment #2) I had crashes on bare metal and virtualized Guests XEN: Hypervisor version 4.7 affected 11.2-RELEASE-p3 amd64 affected 11.2-RELEASE-p9 amd64 Is crashed every time in starting the daemon, so I was forced to downgrade to 9.12 Then I was migrating from from openssl-1.0.2r to openssl111-1.1.1b_1 Then after upgrade bind912-9.12.4P1 to bind914-9.14.2, the daemon did start again on all my instances. (In reply to Dirk Meyer from comment #7) Sorry, one bare metal still crashes with bind914-9.14.2 and openssl111-1.1.1b_1.
