我的网站（Wordpress）有时会停止使用消息“无法连接到 Datatabse”。
我检查了 MySQL 的日志文件，发现了以下崩溃信息：

----------
我重新启动了 MySQL，我的网站运行良好。我的 MySQL 版本是：Distrib 10.4.11-MariaDB，适用于 Linux (x86_64) Ubuntu 版本 20。
这种情况在上个月出现过几次。
我之前在一些帖子中搜索过解决方案。
我已经尝试过这种配置：
max_connections = 100
key_buffer = 50M
max_allowed_packet = 10M
thread_stack = 128K
table_cache = 50
但它仍然被击落。
这是我已经找到的关于我的问题的一个来源： MySQL 不断崩溃
有没有人遇到过同样的问题，知道解决方法吗？
