6100-05-02-內存bug（0509-161）
一天下午接到應用管理員打電話說IC卡AP02主機居然登錄不上去了，但是ping能通，業務居然也正常，於是急忙跑到ECC機房檢查果然如此，經過檢查和測試問題不光在ssh命令上，大部分32位程序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進程， 在ps -ef 顯示出全部，在對比出哪些是32bit程序，（因為業務是java 64bit的所幸沒有影響O(∩_∩)O！）
於是想到了是不是為AIX系統bug，報給IBM主場經查確定為BUG （如果哪位管理的系統還有這個版本的一定要主機升級了撒，重要的事情標紅，就不說三遍了）
目前版本為6100-05-02,在6100-05-03上解決
