在单位内网上安了个discuz, 突然出现论坛不能登录，输入用户名、密码，点击登录后出现如下提示：

iscuz! info: MySQL Query Error

Time: 2007-5-24 9:45am
Script: /discuz/logging.php

SQL: SELECT count, lastupdate FROM cdb_failedlogins WHERE ip='10.65.64.189'
Error: Table '.\discuz\cdb_failedlogins' is marked as crashed and should be repaired
Errno.: 145

Similar error report has beed dispatched to administrator before.

请问这是怎么回事，如何解决，谢谢！

数据表坏掉了
用repair.php修复
