You need to terminate disconnected root sessions.


Log on via ssh to the machine.
Run the following command to list all sessions:
# w
Now you cat terminate a session by killing it's parent process, called the session leader.
Find process id with:
# ps -dN | grep pts/<number>
Kill session using process id returned by ps command
# kill -9 <pid>

To terminate a session using username run the following command:
# pkill -KILL -u <username>
