Comment 1 Robert Rati 2011-04-21 18:42:00 UTC 
Repro with the following entries:
QMF_BROKER_HOST=host1
ENABLE_ABSENT_NODES_DETECTION = TRUE

In addition to other normal triggerd config.
Comment 2 Robert Rati 2011-04-21 20:52:05 UTC 
The setup of the qpid/qmfv2 connections didn't handle exceptions, which would be thrown if the broker wasn't reachable.

Fixed upstream on V7_6-branch
