That means you've got another copy of sc_serv/ices running outside of Centova Cast's control. That can happen if, for example, the pid files for a previous instance got deleted or somesuch. Can also happen if your permissions get out-of-whack -- /usr/local/centovacast/sbin/fixperms would fix that.
In any case, killing sc_serv and ices and then starting them from within Centova Cast again should fix it.
