after booting a CentOS 4.2 system
I have a bunch of zombies...
root 2828 0.0 0.0 0 0 ? Z 14:41 0:00 [chvt] <defunct>
My read from googling this is chvt stems from something that involves a shell.
They ***may*** have been created from my attempts to start mysqld which isn't working (I will start another thread) but no efforts to kill them off are working...
[root@srv1 certs]# kill 2828 [root@srv1 certs]# kill -9 2828 [root@srv1 certs]# ps aux|grep 2828 root 2828 0.0 0.0 0 0 ? Z 14:41 0:00 [chvt] <defunct>
How do I clean this up?

Use "ps auxwwf" to figure out what are the zombies parents and kill the parents. Whenever a process ends/dies/is killed it is turned into a zombie until it is 'reaped' by it's parent process (the parent process needs the zombie to stay around until it receives the SIGCHLD signal and retrieves the process exit state). If a program has children but fails to reap them (either because it doesn't handle SIGCHLD or reap in some other manner) via lack of such facility or bad design or because it froze, zombie processes may accumulate...
Cheers, MaZe.

That was interesting...I have to remember that...
ps auxwwf (the answer to WTF) ;-)
I was able to kill them off at the top
Thanks

Is this because I disconnected monitor and rebooted?
