If we use the ChannelSet configuration which have 2 channels (e.g., one for RTO us-east-1 and another for us-east-2) in the EMAConfig.xml, if encountered problem (received 'CLOSED' stream state status message, e.g., 'DACS force logout'), will the EMA automatically try again the same or switch to another channel, or do nothing at all which requires uninitialize/newOmmConsumer/redo subscribe?
