Step #1: First, you need to find out process PID (process id)

Use ps command or pidof command to find out process ID (PID). Syntax:
ps aux | grep processname
pidof processname

For example if process name is lighttpd, you can use any one of the following command to obtain process ID:
# ps aux | grep lighttpdOutput:

lighttpd  3486  0.0  0.1   4248  1432 ?        S    Jul31   0:00 /usr/sbin/lighttpd -f /etc/lighttpd/lighttpd.conf
lighttpd  3492  0.0  0.5  13752  3936 ?        Ss   Jul31   0:00 /usr/bin/php5-cg

OR use pidof command which is use to find the process ID of a running program:
# pidof lighttpdOutput:

3486

Step #2: kill process using PID (process id)

Above command tell you PID (3486) of lighttpd process. Now kill process using this PID:
# kill 3486
OR
# kill -9 3486
Where,

    * -9 is special Kill signal, which will kill the process.

whiptail is a library that provides the ability to provide dialog boxes from withing shell scripts. Effectively it tries to be an improvement on ncurses. This normally means that a shell script is waiting for some form of user input. I would expect that you could view the manpage for it on your system....but if not you can find the details here:

http://linux.math.tifr.res.in/manuals/man/whiptail.html 

It is used by a number of other libraries/applications including:

  alsa-utils
  signing-party
  rcconf
  module-assistant
  modconf
  gkdebconf
  ubuntu-minimal
  psfontmgr
  pppoeconf
  pppconfig
  gdm
  friendly-recovery
  defoma
  debian-goodies
  debconf
  alsa-utils

The difficulty here is normally trying to find out what application is calling this 'rogue' whiptail routine that is driving up the CPU use up. In your case, it is nice and easy. The remaining bits in your ps output tell us where the problem is. The problem is that your otrs (Open Source Ticket Request System) has not been correctly configured. You can safely kill the whiptail process, but at some point you need to sort out your otrs configuration on that system, or if you are not using it, Perhaps time to clean it up and remove it?

HTH:)

Unfortunately after killing the process everything IS NOT OK. You have merely sorted out the symptoms (excessive processor use), but this issue will return either periodically, or after your next restart. You need to sort out the cause of the problem as detailed above. Either remove or correctly configure your Open Source Ticket Request system.

If by 'killing the app' you actually mean that you have removed the Open Source Ticket Request System, then you should be OK, and I apologise for the misunderstanding of your post.
