I am still trying to gather information to send you a message that caused
the defunct process.  I had over 600 df files in the inbound queue that I
made a copy of before commenting out the UnpackOle line.  Which one would be
the one you need?  Would it be the oldest one?  Is there some attibute about
the file that I can search for to pinpoint the bad one? Or should I just tgz
all of them and put them on a web server for you?

I apologize for not getting back to you sooner with the needed info.  We
have a major site upgrade going live in a few days so I have had to focus on
