Does the htdig process get very big?

It would probably help to run htdig with a single '-v' option so that you can
see what page it is working on when it stops. (Make sure you either redirect
the output or run htdig from within 'script' because there will be a single
line per web page and it sounds like you have a lot of pages...)

If all else fails, you could also run indexes on smaller chunks of your tree
and merge them together to get the full index.
