错误信息：
[Note] mysqld (mysqld 10.3.31-MariaDB-0ubuntu0.20.04.1-log) starting as process 211 ...
/docker/entrypoints/mariadb.sh: line 65: 211 Illegal instruction mysqld ${cmd_mysqld_opts}
amavisd又卡死了，重启了一下docker容器，好了没几分钟，突然就崩了，mariadb疯狂重启，log里显示：INFO success: mariadb entered RUNNING state, process has stayed up for > than 0 seconds (startsecs)。
INFO exited: mariadb (terminated by SIGILL; not expected)
重启容器之后容器内开始反复出现一开始的错误信息，重新拉取镜像也无果。一时间想不出什么办法就用docker system prune -a把docker系统清理了一遍，再次运行docker-compose up -d，奇迹般的好了。
最后也没搞明白是什么原因，重启容器重拉镜像都没用，为啥一清理就好了？
