First, on a long shot, does it help to do close(1) instead if simply close(). I don't think it will but worth a try. Second, I think there is a small leak in the tkcanvas, but not in matplotlib proper. Do you need to display the graphs you are creating, or do you merely want to save them? If the latter, simply use the Agg backend import matplotlib matplotlib.use('Agg') *before* you import pylab. Finally, if you are still having troubles, post a complete, free-standing, script to the matplotlib mailing list and we'll see if we can replicate it.
