My question is exactly the same as another one posted in 2012 I think it was, most recent comment Jan 2015 (oops, forgot username, sorry). I just read down through all responses, no fixes and the question is marked as Unanswered. Anyway we show no data for this resource for any nodes, so I suspect it's something common to all nodes but my polling engine looks okay plus I have other data elsewhere in NPM. Any thoughts are welcome.
