Thank you for your response.  The stderr from that was:

Nice to hear from you again, Paul.  It's been a long time.

That seems to have done it.  I've moved all of those files out as they
were of several different lengths and restarted the command.

It's running now. Will this complete the factorization or will I need
to manually perform any other steps after this?

Thank you both for your help!  I'll share my results with the group if
anyone is interested.

Cheers,
David Willmore
