当我检查 MySQL 下数据库的大小时，我得到以下信息：

MariaDB [(none)]> SELECT table_schema "Data Base Name",  sum( data_length + index_length ) / 1024 /  1024 "Data Base Size in MB",  sum( data_free )/ 1024 / 1024 "Free Space in MB"  FROM information_schema.TABLES  GROUP BY table_schema;
+--------------------+----------------------+------------------+
| Data Base Name     | Data Base Size in MB | Free Space in MB |

| alfresco           |         245.75000000 |      34.00000000 |

我们想找出导致 MySQL 吞吐量达到峰值的原因。以下是崩溃中的 bin 日志列表：

我正在尝试将从正在运行的服务器（将升级到）获取mysqldump的drupal数据库备份导入到运行. 导入失败并出现以下错误：MySQL 5.05.5MySQL 5.5.23

当我在线打开备份时11084，我得到的是：
