how did you restart it? Did you use the init script?

Did you see the reload event in nagios.log? If not, the reload didn't  
happen. If you did see the reload event but still see the host in the  
web interface you either didn't remove it from a file that nagios is  
reading or you still have multiple nagios daemons running.

I can't explain it as it doesn't really make sense. If you reload  
nagios and you don't see the changes in the GUI, either the reload  
didn't happen for some unknown reason, you didn't make the change in a  
file that nagios is reading or you still have multiple nagios  
processes running.

Do you use pre-caching? That's a feature that I don't have experience  
with but may explain your symptoms. http://nagios.sourceforge.net/docs/3_0/faststartup.html
