Is there a message in the debug pane? If so you can use the Search feature to search for the node id in the message in the debug pane.

No this message ins only in the node-red-log. And this node may be from node.js and not from the node-red

This is an error from nodejs itself, so can't tell from that what is causing it. It's a warning rather than an error though so not a big problem while we figure it out..

One of the nodes you have added is probably not handling redeploys correctly and is adding another listener for inputs each time you deeply. (Is usually the problem)

Or, there actually are 11 clients listening... isn't there a setting that allows you to bump up that warning threshold?

True, but only inside the node in question . whichever that is...
