I have not done much with GroupWise 2012 so I apologize for this question, my customer is having an issue with the document viewer agent (gwdva) and I really do not know the answer, but I thought I would post here, please see the following,

most locations have a single post office, about 3 or 4 locations contain multiple post offices. I have read through the documentation, but I have not found a definitive answer on how to configure multiple copies of the gwdva to run in a cluster environment where it is possible that more than one gwdva may need to run on the same cluster node.

Can the agent run twice on the same cluster node (or is this like the POA or MTA that can only have one because of a port conflict?)

Any assistance would be helpful,
