> Funnels can become permanently stopped if they are loaded from a template or 
> if NiFi is ever restarted with nifi.flowcontroller.autoResumeState= is set to 
> false. 
> The only way to get data flowing again is to replace the permanently stopped 
> funnels with new funnels.  There is no way to select a funnel and hit play 
> (ineligible component).  
> Templates that contain funnels are not usable without being manually fixed 
> after addition to the graph.
> If a NiFi instance is ever restarted  with auto resume state set to false, 
> every funnel on the graph will need to be replaced.
