Hi, when ArangoDB is hanging at this point (I am talking about the DBServer) then this usually means that the server has trouble contacting the agency. And this is because the agency is not properly started:
--agency.activate true is missing. This is the central flag that is activating the agency. So in fact you started the agency as a normal single server instance and the dbserver tries to contact an agency there. This won't work. Furthermore if setting up a 3 server agency you have to provide --agency.my-address so that the agents can communicate how to reach them. This should fix your setup. This is however a big usability problem. The exact same happened to me a while ago. I will discuss internally that we improve the startup logging so that arangodb will clearly report in which mode it is starting. Kind regards, Andreas Streichardt Am Mittwoch, 11.
