No notification_options or contact_groups. What are they? Check  
objects.cache.

Yes, nagios will run a host check and if it returns non-OK,  
notifications for the service will be suppressed. What do you see in  
nagios.log related to the host?

Do you get notifications at all, for anything? Verify that you haven't  
disabled notifications program wide (in nagios.cfg or via the web  
interface) or for this specific service (via the web interface). I  
tend to look in status.dat for that information but it can be found in  
the GUI under Program Info and the specific service.
