[LucasYao93]

问题描述及重现代码：

程序运行过程中，偶发的抛出Status unavailable, waiting for recovery. Authentication to host 'localhost' failed. 后自动恢复。

数据库连接信息：
Server=localhost;Port=3306;Database=epams;Uid=root;Pwd=root;Charset=utf8mb4;Min Pool Size=50;Max Pool Size=200;

以下是堆栈信息

字面理解就好，物理连接问题。这个问题freesql链接池背锅已久，意思让你们用ado.net链接池。
