That is from portsentry----
check /etc/portsentry/portsentry.conf
& I think there is also a bug report / feature request to have options for what exactly is reported to you via the WHManager , double check that. If not you'll want to make a new enhancement bug request.
if you find what you'd like to disable in portsentry config, then /etc/rc.d/init.d/portsentry restart -- to get the changes you wanted activated.
