我希望这个问题不是太模糊,但我看得很远但却找不到任何有用的错误.
我有一个.NET 4.5.2 Web服务层(使用ServiceStack和Dapper),自从我们部署服务以来,它几乎没有收到这两个错误.
第一个错误：

我的堆栈上有一点背景：
> .NET 4.5.2
> Dapper 1.50.2.0
> ServiceStack 4.5.4
> MySQL 5.6(使用Amazon Aurora)
我们在任何其他环境中都没有收到此错误,我们没有运行Aurora,只是在Amazon RDS上运行MySQL 5.7.17.
正如我所提到的,这些错误是偶发的,并不总是发生在相同的方法/服务上,但它们总是在使用Dapper从服务层到MySQL数据库执行SQL命令时发生.
有没有进一步调试这个或者是否有任何与MySql / Aurora / Dapper相关的已知问题？经过研究,我找不到任何东西.
