Hi list: Just a little update on the situation: it appears that if I add a node in ANY of the three data_sources that I have, the data_source in question would go down.
I am starting to wonder if it is because of the switch. This data_source is a BladeCenter from IBM and it has a built-in D-Link switch which supports multi-tasking. The other data_source is either hooked into a Cisco switch or a HP Procurve switch (the headnode is hooked into the Cisco switch). Any chance multi-cast is treated differently by the different switches?
