I'm the dovecot maintainer for FreeBSD. To get DEBUG symbols, if you are building your own package, add:
WITH_DEBUG_PORTS=mail/dovecot To your /etc/make.conf, and the symbols should then be available. -- Larry Rosenman http://www.lerctr.org/~ler Phone: +1 214-642-9640 E-Mail: larry...@gmail.com US Mail: 5708 Sabbia Drive, Round Rock, TX 78665-2106 On 11/22/18, 5:42 AM, "dovecot on behalf of Stephan Bosch" <dovecot-boun...@dovecot.org on behalf of step...@rename-it.nl> wrote: Op 22-11-2018 om 3:47 schreef Bert JW Regeer: > It happened again: > I really wish I could get some better backtrace information, but unfortunately this is it :-( Did you install the debug symbols for Dovecot? On Debian, those are available as a separate dovecot-dbg package. I'm not sure how FreeBSD provides this.
