EventEmitter memory leak (after adding 11th listener) #1721

Closed JimCSaratoga closed 2 years ago

JimCSaratoga commented 2 years ago

Description While running a HOOBS box (recently upgraded to Version 4.1.18, Node Version 16.13.1, Homebridge 1.3.8) with a single plugin: Platform InsteonLocal Bridge version 0.4.21 I've run into a Max Listeners Error after adding my 11th Insteon device. The node error is (node:13124) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 connect listeners added to [Insteon]. Use emitter.setMaxListeners() to increase limit Upon rebooting the HOOBS, the same error was encountered but this time with (node:660)

Additional context The error first appeared after adding the 11th device. Not sure where I can go on HOOBS to increase the # of listeners but also am not sure if that is an actual proper step.
