In my case.  I was fooling around with the bb-stocks.sh script from
deadcat.net, running it from hobbitlaunch.cfg on the server.  It sends
reports where the hostname is the ticker symbol (e.g. IBM, MSFT, etc) and
the column name is "stock".  I let it run for a while, then marked the entry
in hobbitlaunch as DISABLED and dropped the stock names.

This morning, while reading this email thread, I went back to the script and
inserted "exit" right at the top, so it shouldn't be possible for the script
to produce a report, even if it gets launched.

The ticker symbols do *not* show up in the hobbitdboard output.  They *were*
in the data/hist/allevents file, but

     trimhistory --cutoff=`date +%s --date="19 May 2008"` --drop

took care of that.  I've confirmed via grep that the names do not appear in
any file in the Hobbit directory hierarchy.

I *do* still see the ticker symbols in  "bb localhost ghostlist", but they
don't appear in the Ghost Clients web page.

Maybe I'm missing something obvious.  Here's a quick test if you're
interested in replicating the problem:

   server/bin/bb localhost "status server,domain,com.bogus green `date`"
   server/bin/bb localhost hobbitdboard | grep server
   server/bin/bb localhost ghostlist | grep server

server.domain.com should not ever have existed in your bb-hosts file.  It
will show up in the Ghost Clients web page for 5 minutes.  45 minutes after
doing the above, it's still showing in "bb localhost ghostlist".
