(No output returned from host check)

[Albert Whale]

What is this error?

I am getting this on the Nagios Server, which is odd, because it is the 
performing the monitoring.

I suspect this may be a firewall issue, but not knowing what is 
generating this message and reporting Host Status Down, I am not able to 
resolve this.

What causes this message?
