6100-05-02-内存bug（0509-161）

一天下午接到应用管理员打电话说IC卡AP02主机居然登录不上去了，但是ping能通，业务居然也正常，于是急忙跑到ECC机房检查果然如此，经过检查和测试问题不光在ssh命令上，大部分32位程序在执行的时候都会报错，如resize等。

处理过程：

使用ps -efM 筛选出64bit进程， 在ps -ef 显示出全部，在对比出哪些是32bit程序，（因为业务是java 64bit的所幸没有影响O(∩_∩)O！）

于是想到了是不是为AIX系统bug，报给IBM驻场经查确定为BUG （如果哪位管理的系统还有这个版本的一定要主机升级了撒，重要的事情标红，就不说三遍了）

目前版本为6100-05-02,在6100-05-03上解决
