You normally do not want to use 'is_volatile' for passive service
checks. They should only be used for services that automatically reset
themselves to an OK state after being checked and you wish to be
notified _every_ time they're checked and not OK. This would account for
your multiple notifications.

 http://nagios.sourceforge.net/docs/2_0/volatileservices.html

Volatile services differ from "normal" services in three important ways.
Each time they are checked when they are in a hard non-OK state, and the
check returns a non-OK state (i.e. no state change has occurred)...

    * the non-OK service state is logged
    * contacts are notified about the problem (if that's what should be
done)
    * the event handler for the service is run (if one has been defined)


These events normally only occur for services when they are in a non-OK
state and a hard state change has just occurred. In other words, they
only happen the first time that a service goes into a non-OK state. If
future checks of the service result in the same non-OK state, no hard
state change occurs and none of the events mentioned take place again.
