The router(s) in question is sending flows to two harvesters connected to the same NFA console. The console is consistently reassigning the router to each of the harvesters and the graphing becomes degraded.
The router's configuration needs to be edited so that it is only sending data to one harvester. You should also investigate the possibility of a 'cloner' forwarding flows to a second harvester unintentionally.
