attempt to access beyond end of device很危险

最近帮助客户处理了一次数据库异常，异常导致数据库崩溃，以ORA-00600 4193/4194错误无法启动，系统表空间数据文件出现坏块。

检查操作系统日志时，发现有如下提示信息：

关于attempt to access beyond end of device的错误，以前也曾经遇到过一次，请参考案例：圣诞超级复杂困难之Oracle数据库大恢复
这类提示的具体原因我不是很清楚，估计是在读写文件时出现地址越界，导致数据库故障。

系统是Linux环境，Release:    2.6.9-34.ELhugemem，最后通过备份帮助用户恢复了数据。
