I'm running the following:
# 2.3.4 (0ecbaf23d): /usr/local/etc/dovecot/dovecot.conf
# OS: FreeBSD 11.2-RELEASE-p4 amd64
# FS: ZFS
auth_mechanisms = plain login

listen = *
mail_location = maildir:~/Maildir
namespace inbox {
inbox = yes
location mailbox Drafts {
auto = subscribe
special_use = \Drafts
}
mailbox Junk {
auto = subscribe
special_use = \Junk
}
mailbox Sent {
special_use = \Sent
}
mailbox Trash {

special_use = \Trash
}
prefix }
passdb {

}
protocols = imap lmtp
service auth {

user = postfix
}
user = dovecot
}
service imap-login {
inet_listener imap {
port = 0
}
}
service lmtp {
unix_listener /var/spool/postfix/private/dovecot-lmtp {

}
}
service stats {
unix_listener stats-reader {

user }
unix_listener stats-writer {
group = $default_internal_group

user }
user = $default_internal_user
}
ssl_cert = </root/cert.pem
ssl_key = # hidden, use -P to show it
userdb {
driver = passwd
}
dmesg shows:
pid 74441 (imap), uid 1002: exited on signal 6
pid 74784 (imap), uid 1002: exited on signal 6
pid 21471 (imap), uid 1002: exited on signal 6

pid 21464 (imap), uid 1002: exited on signal 6
pid 21731 (imap), uid 1002: exited on signal 6
Sometimes the dovecot process serving an user crashes. He runs mostly
airmail on macOS and samsung mail on Android.
Happens only to that particular user.
The log shows the following: (maillog)
Dec 16 14:52:35 mail dovecot: imap-login: Login: user=<USER>,

I'm here if more info is needed.
Thanks for taking a look.

The bug happens not very often, it might need a week to get a core file.
