怎么会ORA-00471: DBWR process terminated with error

各位大虾，小弟在此请教了，一般oracle会在什么情况下出现这个问题啊。日志如下：
alert.log
>;
>; Thu Sep 16 14:19:59 2004
>; Errors in file /opt/oracle/admin/ora92/bdump/ora92_pmon_25408.trc:
>; ORA-00471: DBWR process terminated with error
>; Thu Sep 16 14:19:59 2004
>; PMON: terminating instance due to error 471

察看最早是由什么进程引起的，并察看相应trc文件找到问题。

再早就没有了啊，前一次的alert.log日志是十天前的啊。

看看这两个trc
/opt/oracle/admin/ora92/bdump/ora92_pmon_25408.trc
/opt/oracle/admin/ora92/bdump/ora92_ckpt_30564.trc
