Ok. This is a possible false alarm. Found evidence that my children are exiting unexpectedly. I'll need to cleanup the opts._workers array to keep things current.

This small addition to my code solves the issue for me.

cluster.on('exit', (worker) => {
	// cleanup from LE workers array if the worker exits
	let widx = leOptions._workers.findIndex(w => w.id === worker.id);
	if (widx !== -1) leOptions._workers.splice(widx, 1);
});

And its necessary as greenlock-cluster/master.js creates an array of workers via the addWorker method (line #26). If those workers die or get killed externally for any reason then the attempt to broadcast to all of them on line #80 fails with ERR_IPC_CHANNEL_CLOSED.

FYI: as an optimization, it may be simpler to rely on the hash of active workers provided by the cluster module.

Otherwise, adding the code above to the documentation would be helpful to new users relying on this module.
