发现线上系统几小时就会发生内存溢出，通过排查找到系统中大量SequelizeConnectionError异常信息。 { [SequelizeConnectionError: Cannot enqueue Quit after fatal error.] name: ‘SequelizeConnectionError’, message: ‘Cannot enqueue Quit after fatal error.’, parent: { [Error: Cannot enqueue Quit after fatal error.] code: ‘PROTOCOL_ENQUEUE_AFTER_FATAL_ERROR’, fatal: false }, original: { [Error: Cannot enqueue Quit after fatal error.] code: ‘PROTOCOL_ENQUEUE_AFTER_FATAL_ERROR’, fatal: false } } Promise { _bitField: 18087936, _fulfillmentHandler0: { [SequelizeConnectionError: Cannot enqueue Quit after fatal error.] name: ‘SequelizeConnectionError’, message: ‘Cannot enqueue Quit after fatal error.’, parent: { [Error: Cannot enqueue Quit after fatal error.] code: ‘PROTOCOL_ENQUEUE_AFTER_FATAL_ERROR’, fatal: false }, original: { [Error: Cannot enqueue Quit after fatal error.] code: ‘PROTOCOL_ENQUEUE_AFTER_FATAL_ERROR’, fatal: false } }, _rejectionHandler0: undefined, _promise0: undefined, _receiver0: undefined }
几乎是同一套系统部署在不同服务器上，其中一个服务出现上面sequelize异常。 请问大家这是是mysql连接池的问题吗，目前连接池最大连接是30，有没有哪位同事碰到过类似问题？
