6100-05-02-記憶體bug（0509-161）

     一天下午接到應用管理者打電話說IC卡AP02主機居然登入不上去了，但是ping能通，業務居然也正常，于是急忙跑到ECC機房檢查果然如此，經過檢查和測試問題不光在ssh指令上，大部分32位程式在執行的時候都會報錯，如resize等。

處理過程：

使用ps -efM 篩選出64bit程序， 在ps -ef 顯示出全部，在對比出哪些是32bit程式，（因為業務是java 64bit的所幸沒有影響O(∩_∩)O！）

于是想到了是不是為AIX系統bug，報給IBM駐場經查确定為BUG （如果哪位管理的系統還有這個版本的一定要主機更新了撒，重要的事情标紅，就不說三遍了）

目前版本為6100-05-02,在6100-05-03上解決

BUG資訊如下：
