global event handlers firing sporadically in 1 .1

[Andreas Ericsson]

Silly question, maybe, but is enable_event_handlers explicitly set to 1 
in all templates that these hosts and services use?
If I remember the code correctly, lower 'levels' of configuration have 
first priority in a 'laziest possible' way (nagios won't do anything if 
any of the levels it has to check tells it not to).

Cheers,
Sourcerer / Andreas Ericsson
