优化表后出现了is marked as crashed and last (automatic?) repair failed
今天想优化一下表，优化之后出现了如下问题：

SQL code

<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->mysql> OPTIMIZE TABLE jo_mailqueue;+---------------------+----------+----------+-------------------------------------------------------------+| Table               | Op       | Msg_type | Msg_text                                                                                        |+---------------------+----------+----------+-------------------------------------------------------------+| jobour.jo_mailqueue | optimize | error    | 1 when fixing table                                                                             || jobour.jo_mailqueue | optimize | Error    | Can't change ownership of the file '/usr/local/mysql/data/jobour/jo_mailqueue.MYD' (Errcode: 1) || jobour.jo_mailqueue | optimize | status   | Operation failed                                                                                |+---------------------+----------+----------+---------------------------------------------------

从phpmyadmin打开之后，发现表正在使用中。


OPTIMIZE 优化表怎么会出现这种问题啊。是什么导致的啊。？ 谢谢！
