There are sometimes that some tasks, or programs have not been finished and are in a dead lock situation. There tasks doesn't die even if you have logged off and logged in. These process are still running and cannot complete as they have become unstable and are in a dead lock which needs to be manually terminated...

Use the process status command to list all the running process :

sudo ps

Then use kill command to kill the process by its PID that you want to kill...

kill 321

All the best!
