Even in a team of one there is need and means for doing something like this. For myself, I call it a "lessons learned" session.
I find a quiet space and get my yoga Zen on. I review the problem, its symptoms, how the tasks of problem determination and problem resolution unfolded, and places in that sequence where I got off on the wrong track and why. Sometimes I add technical information to my web site to use as a memory aid for the next time I encounter these symptoms or something similar.
You are correct; you can add swap space without turning off the existing swap space. It is much safer to stop as many programs as possible and turn of any existing swap space -- *if possible*. Also, preallocating the swap file as you have makes the swap file a bit faster than allocating it when it is needed. The scenario I used is a bit more ideal than yours.
As with almost everything Linux there are many options for everything you might need to do. The one that works best for you is clearly the one you should use.
Thanks for your comment.
