.cfc-files make program hang

in my multi-category classifier, i have a weird problem; after a
period of inactivity, i have to re-create the .cfc-files from scratch
to make the classifier program run properly.

example: i help train my classifier for a while, and then leave the
program open and go home from work. when i come back in the morning
and continue, the program hangs for several minutes, or even longer
(sometimes for more than an hour, in which case i shut down and start
over).

this also happens if i go for lunch, or even if i take a few minutes
off from classifying. the program is always slow after the break.

i have also seen the program hang like this on 'virgin' .cfc-files
that were created the day before, but not used.

it seems that somehow, my .cfc-files magically 'rot' or go stale. how
on earth is this possible?

i use nineteen categories. could this have something to do with it?

the program i have created is text-based, and runs in the terminal. it
tries to classify an article, and presents the user with a suggestion
(along with an excerpt from the article). the user then answers 'y' or
the right category.
