This is not working as designed.  I often see plugins time out (for whatever
reason) but the plugin just returns a Critical status and are treated
properly as such.  Nagios can not tell why the result was generated; only
that the plugin returned "Critical".

When this happens, what does the "Attempt" column say? (what out of what)?

Also, are you sure you're not confusing a host alert with a service alert?
If the host check fails (which will be checked as a result of even one
failure on a service), you will get a HOST alert for the device, NOT a
service alert.  The host alerts use a different set of configuration
parameters.
