You mention plotting.  I'd suggest checking  that you aren't holding
state inside matplotlib, which is exceedingly easy to do without
noticing if you only use the pylab/pyplot interface and don't take
care to clear things out.

As a quick check, disable the plotting by commenting the plot commands
out, but leave the rest of the code to run.  That will help isolate
whether the problem is indeed in your plotting code.
