notification_interval seems to be ignored

[Zembower, Kevin]

I've written a custom plug-in to monitor the ambient temperature probe
on my Dell PowerEdge server. It's a wrapper around the standard
check_smtp plugin. It's been working correctly for months now. I pasted
the code for this in at the end of this message.

Yesterday at 2:00 the compressor failed in my server room and the
temperature went up to 90F. My notification was correctly sent, and I
was happy. However, I've received a notification every 5 minutes since
then that the temperature is over 80.

In the service definition, I have notification_intervals set to 0:
# check that ambient temperature from Dell sensor is less than 80 and 90
degree F.
# Notify the 'temp' group only.
define service {
        hostgroup_name                  temp_sensor
        service_description             Ambient Temperature 
        check_command                   check_ambtempF!80!90
#For testing, set the temperature too low
#       check_command                   check_ambtempF!60!70
        use                             generic-service
        notification_interval           0; set > 0 if you want to be
renotified
        contact_groups                  temp
}

In generic-service.nagios2.cnf, the notification_interval is also set to
0. Furthermore, I don't have any escalations defined.

And, I just discovered that even though I disabled notifications for
this service using the nagios2 GUI, I'm still getting notified every
five minutes.

Can anyone suggest anything I can try to fix this behavior? Did I
overlook something in how I wrote the plugin?

My system is Nagios 2.6, as installed by the Debian 3.0 package system.

Thanks for any advice or suggestions.
