Oracle 10G的一个BUG

一台Oracle数据库出现告警，发现已经非法关闭了，但是查看alert等信息并没有其他异常信息。 使用sqlplus或者查看lsnrctl等信息时一直挂在那里不动。

环境：

OS：CentOS 6.3
DB：Oralce 10.2.0.1.0

数据库版本是10G，猜测是不是一个BUG引起的，就查看一下

ps -ef|grep sqlplus 
oracle    8702  8701  0 11:00 pts/6    00:00:00 sqlplus             --hang住了
oracle    8792  8744  0 11:00 pts/7    00:00:00 grep sqlplus

--跟踪进程分析：
strace -p 8702

times(NULL)                             = -2140814387
times(NULL)                             = -2140814387
times(NULL)                             = -2140814387
times(NULL)                             = -2140814387
times(NULL)                             = -2140814387
times(NULL)                             = -2140814387
times(NULL)                             = -2140814387
times(NULL)                             = -2140814387
times(NULL)                             = -2140814387
times(NULL)                             = -2140814387
times(NULL)                             = -2140814387
times(NULL)                             = -2140814387
times(NULL)                             = -2140814387
times(NULL)                             = -2140814387
times(NULL)                             = -2140814387
times(NULL)                             = -2140814387

查下系统运行时间
[oracle@localhost ~]$ uptime
10:56:57 up 199 days, 16:02,  4 users,  load average: 55.99, 55.85, 53.78

果然是一个以前遇到过的调用时间函数死循环的BUG，翻了一下，
参考：

It is looping on the times() function.

In addition to sqlplus, it has been reported that the netca and dbca tools also hang.

Changes

This may happen with a new installation of Instant Client 10.2.0.1.0 or Oracle 10.2.0.1.0 on UNIX platform, or it can just occur after some period of time with no other changes. 

Cause

This is a known, unpublished bug.

二、处理
该问题重现的周期在250天左右，已在11G版本被修复； 
临时解决，先把应用停掉，再删除oracle进程，最后reboot服务器；
最终解决：打补丁，或者升级到11G
