检查补丁PSU 9655006 readme；发现该PSU Bug fixed 中存在：
9356344 - ORAROOTAGENT BURNING CPU, LEAKING MEMORY AND THREADS
并在PSU 9655006中解决了orarootagent内存泄漏的为您提。同时，确定补丁
9655006确实应用成功了: applied on Wed Aug 25 14:13:20 CST 2010

但检查list的Bugs fixed中，Cluster Ready Services部分的很多Bugs号都
没有，包括9356344，为什么？

版主帮忙看看呀！！

这个难道我了，仔细看下你资源那些是不是消耗了没释放！学习下。

[ePower518]

应该是释放了的？没有额外的或者死进程。不知道，还需要看哪些方面，资源是否释放？
