dovecot aut-worker 致命

Question

我已经使用 dovecot 设置了一个测试服务器，并在 mail.warn 中收到此错误

dovecot: auth-worker: Fatal: master: service(auth-worker): child 6169 killed with signal 11

我的 dovecot.conf 与这里相同：https://thomas-leister.de/mailserver-debian-stretch/#hauptkonfigurationsdatei-dovecot-conf

我在谷歌中发现了这个错误，并在 dovecot.conf 中插入了一个 auth-worker 块

service auth-worker {
    user = dovecot
    unix_listener auth-worker {
        user = dovecot
    }
}

但没有运气。
