一套HP-UX上的9.2.0.5系统在shutdown abort时出现ORA-00600: internal error code, arguments: [OSDEP_INTERNAL], [], [], [], [], [], [], []内部错误，伴随有ORA-27302: failure occurred at: skgpwinit4，ORA-27303: additional information: attach to invalid skgp shared ctx，具体日志如下:

经查该内部错误与操作系统共享内存有关，相关的Note有:

不恰当的设置OS VM参数可能导致该问题，而在HP-UX PA-RISC平台上使用'shotdown abort'命令时可能因为共享内存未能正常移除而出现该内部错误；因为实例还是以'abort'方式关闭的，仅仅是共享内存未能释放，所以只需要以ipcs->ipcrm等os命令将相应的共享内存段释放就可以了，不会造成其他影响。
