数据库突然发生了不能查询的情况
请高手们给点指点，新手，比较白。每次来了都是光看，不发贴，潜水。现在出了问题才知道注册，这样确实有点无耻||||我错了。求指点。。
昨天突然发生了不能正常查询的错误，查的时候提示：The connection has been marked dead.
被标识为DEAD？
错误日志是这样

这是什么意思，初始化的时候发生了什么错误，那几页怎么了。database'4'是自己建立的一个库。。。
很着急。。。求指点...谢谢了

解决方法：
1. 首先找出问题的sysobjects的名，大部分是表或者索引
select name from sysobjects where id=1166624168
2. 如果是一个表的话,对这个表进行
dbcc checktable
dbcc tablealloc
3.在这之后，可以尝试将表bcp out，再bcp in
基本上都能解决此类问题。
