Unable to kill process, even with root. How to diagnose?
1
There are a lot of bash processes running on my Ubuntu Linux (12.04). Even when I close the terminal they are still shown in the System Monitor.
I tried killing them as below, but they remain as it is. How to diagnose the issue, why can't they be terminated?

Do not you think that you can not kill bash in your system? You run an application/program in bash and you can kill a program that runs in bash. Now you find all processes ID programs that run in bash.
as you showed on your terminal:
> user 4660 0.0 0.0 4372 844 pts/7 R+ 10:45 0:00 grep
> --color=auto --exclude-dir=.svn bash
Try to kill that process:
sudo kill 4660
or
sudo kill -9 4660

Do not you think that you can not kill bash in your system? You run an application/program in bash and you can kill a program that runs in bash. Now you find all processes ID programs that run in bash.
as you showed on your terminal:
> user 4660 0.0 0.0 4372 844 pts/7 R+ 10:45 0:00 grep
> --color=auto --exclude-dir=.svn bash
Try to kill that process:
sudo kill 4660
or
sudo kill -9 4660
let me know what happeens

@MatthiasDiener sorry, didn't see the comment earlier. I rebooted PC and now the problem is gone. I had tried killing by PID but it didn't work (i think it gave no output on terminal)

First you need to stop those bash processes then kill it. Also make sure you should either be the owner of the process or a privileged user to kill a process.

@user13107, No output in the terminal means that it worked. Even when
pkilldoes not work,kill -9should most definitely work when running as root.– Peschke
