关于，库日志不能截断的问题!

系统：win xp+sybase 11.9
系统正在使用，报日志满，在系统里面通过，图型窗口进行了日志的备份截断,结果报错：
"Uninitialized logical page '1024007' was read while accessing object '8' in database '7'
Please contact Sybase Technical Support.
The SQL Server is terminating this process."

小弟通过DBCC CHECKALLOC(DBNAME,FIX)进行处理后，的处理结果最后有这样的显示：
在执行修复前是这样的：
Processed 626 entries in the sysindexes for dbid 7.
Found 1 bad entries in the sysindexes.
DBCC execution completed. If DBCC printed error messages, contact a user with System Administrator (SA) role.
Table Corrupt: Attempted to get page 1024001, object 8;  got page 0, object 0.

看结果，好像是修复了2个bad,但是问题还是在。。。
请都各位，这个故障如何下手呢！
谢谢

object 8

看看是个神码东西，然后DBCC
