This is pretty unusual. Please post the host and command definitions.   
For a typical installation, check_host_alive uses check_ping which is  
just a wrapper for /bin/ping. It asks /bin/ping to ping the host and  
parses it's output for the response. Could it have been that IP in the  
config file at any time? Do you have multiple copies of nagios running  
with the older one having seen that IP in the config files?
