我的网站（Wordpress）有时停止使用以下错误消息“

无法连接到数据表

我检查了 MySQL 的日志文件，发现崩溃信息如下：

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。

这种情况在一个月前出现过几次。

我之前确实在一些帖子中搜索过解决方案，但仍然无法解决这个问题，

MySQL 服务器每周至少崩溃 2 次

Wordpress + PHP+ apache +mysql，mysql每1/月崩溃一次

有没有人被困在这种情况下，并且知道如何解决它？
