任何人都知道为什么会这样吗？ 在我实现mysql\_multi以运行MySQL服务的多个实例(一个在端口3306上，一个在端口3307上)之后，它开始发生。 我在Ubuntu服务器上运行MySQL。

Anyone have any idea why this is happening? It started happening after I implemented mysql\_multi to run multiple instances of the MySQL service (one on port 3306, one on port 3307). I'm running MySQL on Ubuntu server.

这里发生了什么：

Here's what happens:
