error preloading the connection pool

这个错误是指在预加载连接池时出现了问题。连接池是一组已经建立好的数据库连接，用于提高数据库访问的效率。可能是连接池配置有误或者连接池中的某个连接出现了问题导致预加载失败。需要检查连接池配置和连接状态，以解决这个问题。

The play() request was interrupted by a new load request

This error message typically appears in JavaScript when you are trying to play a media file using the HTML5 video or audio tag, but another audio or video file is already loading or playing on the same page.

This error occurs because the play() method of the HTML5 media element can only be called when the media is ready to play. If a new load request is made while the media is still loading or playing, the play() request will be interrupted and the error message will be displayed.

To fix this error, you can try the following steps:

1. Wait for the current media file to finish loading or playing before initiating a new load request.

2. Use the pause() method to stop the current media file before initiating a new load request.

3. Use the canPlayThrough event to check if the media is ready to play before calling the play() method.

4. Use a preloading library or technique to ensure that media files are fully loaded before they are played.

By following these steps, you can avoid the "play() request was interrupted by a new load request" error in your JavaScript code.
