Typical log message:
Oct 7 11:39:36 hostname dovecot: imap(username): Fatal: master: service(imap): child 14864 killed with signal 11 (core dumped)
What triggers the problem:
User moving multiple messages to a subfolder via IMAP (from another
account, on another server, client: Thunderbird). Moving single messages
either does not trigger the problem, or with much lower probability
(could not reproduce).
Version:
$ dpkg -l 'dovecot*'
