For those of you that use Lotus Notes professionally, I am confident that you will find a time when Lotus Notes becomes non-responsive. When it gets into this state, and you terminate the process, what happens is that there are remaining processes belonging to notes that continue to run. Without needing to get into the technical background of these process and what the are meant for, the net result of the above situtation is that after killing Lotus Notes, these remaining processes that are running will prevent you from starting it again.
