如何kill一個 zombie process?

發現production環境上有一個zombie,如何殺掉呢?

top - 13:13:38 up 23 days, 19:49,  1 user,  load average: 2.58, 3.43, 3.75
Tasks: 1527 total,   3 running, 1523 sleeping,   0 stopped,  1 zombie

[oracle@oracle02 ~]$ ps aux |awk '{print $8 " " $2}' |grep -w Z
Z 10460

什麽東西呢?
[oracle@oracle02 ~]$ ps -ef |grep 10460
oracle   10460 10431  0 Aug10 ?        00:00:00 [Xsession] <defunct>
oracle   22374 26077  0 13:11 pts/1    00:00:00 grep 10460
[oracle@oracle02 ~]$ kill -9 10460

top發現並沒有去掉,查看一下他的父進程是個啥?

[oracle@oracle02 ~]$ ps -ef |grep 10431
oracle   10431  8971  0 Aug10 ?        00:00:00 /usr/bin/gnome-session
oracle   10460 10431  0 Aug10 ?        00:00:00 [Xsession] <defunct>
oracle   10493 10431  0 Aug10 ?        00:00:00 /usr/bin/ssh-agent /usr/bin/dbus-launch --exit-with-session /etc/X11/xinit/Xclients
oracle   30789 26077  0 13:15 pts/1    00:00:00 grep 10431
[oracle@oracle02 ~]$ kill -9 10431

乾淨了,這個gnome-session是幹嘛的呢?再查一下
