I reckoned there wasn't much to go on. This was more just a case of reporting the fact, in case anyone else sees the issue - since there is a temporary way out.
I'm hoping to be able to replicate the set-up (and issue) on my laptop, so might be able to get more info there. There are no core dumps - dovecot turns them off at start-up: Oct 29 15:39:34 master: Info: Dovecot v2.3.7.2 (3c910f64b) starting up for imap (core dumps disabled) Oct 29 15:39:49 master: Info: Dovecot v2.3.7.2 (3c910f64b) starting up for imap (core dumps disabled) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1902128 Title: Dovecot imapd server producing SIGSEGV in groovy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dovecot/+bug/1902128/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
