Solution / Answer:
The default time-out setting of 30 seconds is too short, for MTA to process request. Change the default time to 120 seconds or more.
Change Nagios notification_timeout settings
Change the setting “notification_timeout” in nagios.cfg
# vi /usr/local/nagios/etc/nagios.cfg
Change the value of “notification_timeout=30″ to “notification_timeout=120″
notification_timeout=120
