PDOException:SQLSTATE[HY000][2002]操作正在进行，在php artisan队列上：工作

我使用的是mysql 8，

php artisan queue:work

每31秒失败一次，下面是错误跟踪。 据我所见，当它想要处理下一个排队作业（#17），然后尝试在trace#21上创建事务，但无法创建与mysql驱动程序的pdo连接时，就会发生这种情况

有人能帮我解释为什么会这样吗？任何提示或方法调试此感谢提前

这是因为另一个使用相同mysql的服务打开了连接，但没有关闭，所以它影响了我的服务。您到底是如何修复的？Sonu Bamniya-因为有人编写代码打开mysql连接，但没有关闭它，这导致了错误，所以修复方法是在您使用完连接后请关闭mysql连接
