[Xymon] Can't clear ghost clients

I've got 6 ghost clients listed on my server webpage. I have a clean hosts.cfg file that definitely does not contain any of the names in the ghost list. The ghost names are from many months ago when I first setup the server. I've since change the names. I've attempted to clear the ghosts using the following commands but it doesn't clear anything. Buzzard is one of the hostnames in question.

#cd /usr/lib/xymon/server/bin

#xymon 127.0.0.1 "drop Buzzard"

Anyone have a clue as to how to clear old ghosts and/or where to find the pesky files that are causing it?

Thank you.
