7 years ago Hi,
This was already reported on #4. That was not really a bug, but just a warning from the EventEmitter we use to propagate the variable changes. This was already fixed on 1.1.2, try updating to the latest version and you shouldn't see this anymore
When I start the node-red I got the following message:
(node) warning: possible EventEmitter memory leak detected. 11 __STATUS__ listeners added. Use emitter.setMaxListeners() to increase limit.
