[ossec-list] How do I kill a ghost OSSEC agent host?

[blacklight]

Hello Folks,

I am trying to get a host that I had removed from OSSEC monitoring
through /var/ossec/bin/manage-agents completely off the list of hosts
in the OSSEC GUI - The host name still remains on the OSSEC GUI but
it's a ghost (or if you prefer, a zombie) - How do I wipe this ghost
out?
