This is one of the big reasons I stopped using NDOUtils - the broker
would regularly block the Nagios process. So yes, you're correct -
your NDOUtils broker is blocking, and nothing is happening during
these periods of maintenance.
That, and the check latency. With NDOUtils, I couldn't let my
Nagios daemons run a full week without restarting them or the
check latencies would shoot through the roof (that's a full restart,
not a reload).
