1. Sometimes programs leave processes running (especially when things go wrong - or abnormally terminate). Rather than just logging off and assuming that they'll go away, you should check that they're not still running.
2. List the processes running under your account using 'ps' (e.g. % /bin/ps -ef | grep 'username' [replace username with your login name]). The second column should list the PID's or process id's.
3. Stop the processes using 'kill -9 <PID>' (e.g. % kill -9 345). You can kill the processes one at a time or combine several PIDs on the same line (separated by spaces) (e.g. % kill -9 345 678 901).

If you have any question, ask or send mail to the consultants.
