There are no known issues with any version of nagios like this.

Looks fine. The implication then is that your check-host-alive command  
doesn't actually do that. The status information at the time this  
happens would be the confirmation of that. When a service goes down,  
check-host-alive is run. If it returns a non-OK state (or fails in  
certain ways), the host status is set to non-OK. When the service  
recovers, check-host-alive is run again to verify that the host has  
recovered. If it still returns a non-OK state (or fails in certain  
ways), the host status will remain non-OK. When you restart nagios,  
check-host-alive is _not_ run. Instead, nagios assumes the host is OK  
as long as the service on the host returns OK.
