Description

Sometimes, on customer environment, some nodes might use same ip for some nics. this is quite common on virtualized environment.

If this case occurs, segment will not be able to register on master. And there is only one 'down' segment in gp_segment_configuration, and the reason shows "resource manager was reset".
