今天有个项目系统负载突然变大，查到top sql是一个存储过程,执行计划缺少合理的索引，SQL是个update操作，于是kill 调用的几个session 建立一个索引，结果发现kill几个用户进程后实例挂了.下面是alert日志，可见instance crash前出现过死锁,就是那个update sql

ksedst()老杨也有遇到过类似案例http://space.itpub.net/4227/viewspace-713527
在MOS上查到最接近的是下面这篇
note ID 443909.1
ORA-00600: internal error code, arguments: [kcbshlc_1], [71], [], [], [], [], [], []
PMON: terminating instance due to error 472
Stack Trace is similar to the following:
ksedst ksedmp ssexhd sigreturn kcbshlc kslilcr ksl_cleanup ksuxfl ksuxda ksucln ksbrdp opirip
