[mysql] 2023/05/19 19:33:49 packets.go:37: unexpected EOF

很明显的网络问题， 读流失败

	var res Result
	var err error
	var isBadConn bool
	for i := 0; i < maxBadConnRetries; i++ {
		res, err = db.exec(ctx, query, args, cachedOrNewConn)
		isBadConn = errors.Is(err, driver.ErrBadConn)
		if !isBadConn {
			break
		}
	}
	if isBadConn {
		return db.exec(ctx, query, args, alwaysNewConn)
	}
	return res, err

驱动层存在重试逻辑， 需要排查网络问题
