当我启动 mariadb 10.4.8 服务器时，我的 error.log 文件中有许多这样的错误消息引用了无法打开的不同文件：
2019-09-30 17:38:19 0 [ERROR] InnoDB: Cannot open datafile for read-only: '/tmp/#sql50b_8808_1.ibd' OS error: 71

我没有名为 的数据库tmp，因此数据字典故障排除说明没有帮助。
我在我的文件系统中找不到任何以#sql任何地方开头的文件，但是
SELECT * FROM INFORMATION_SCHEMA.INNODB_SYS_TABLES
WHERE NAME LIKE '%#sql%';
返回 65 行，包括与上述文件关联的行。有什么方法可以清理它，这样 MariaDB 就不会尝试打开这些不存在的文件吗？
