我使用MariaDB的（21年1月10日）有以下存储引擎：如何解决MariaDB的高内存使用问题？
- InnoDB的
- TokuDB
- 蜘蛛引擎
系统配置为：
- 3GB RAM
- 双核处理器
我试过pt-mysql-summary工具来识别内存使用情况，它显示当服务器上没有进程正在运行时，innodb缓冲池大小的90％被填充。
我也尝试重新启动MariaDB服务器，这只会减少大约1-2个小时的内存，然后它吃掉内存。
任何线索为什么它消耗太多的内存？
分享我下面的配置：

它是否会导致您的问题？数据库爱内存和缓冲池是否有充满缓存的数据... –
是的，但有时它由于高使用率而崩溃。 –
当没有任何东西在运行时，它也使用RAM。有什么方法可以识别这个吗？ –
