Good afternoon I'm upograding my system to latest versions and have error as follows at start: (node:7539) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 ready listeners added. Use emitter.setMaxListeners() to increase limit I have even disabled all flows but still ha…

There isn’t a problem, you have 11 listeners set and if you need then all that’s fine it’s an automatic warning not an error It doesn’t mean there’s actually a memory leak. It comes up in the forum from time to time, I’m sure a search would return an answer from CJ or Nick…

Where I can set the number of listeners for not having the message?

The message tells: Use emitter.setMaxListeners() to increase limit However I don't know exactly where or how I should do this, any tip to follow is welcome. Regards

I think it has to be set in the node causing the problem. However as has been stated, it is just a warning so you should be able to ignore it. It is likely from one of the config nodes which is why disabling the flows does not stop it.

Perfect, thanks boss, I will keep moving forward to complete updates

If you do or can identify the node that would be helpful to try and get it fixed.

I don't know how to search for it, I was trying to enable disable flows but didn't find it, any tip on how to look for it? Regards

maybe there are more lines in the error log than just the one you posted ?
