Error: Service name is already in use on the network
**Describe Your Problem:**
I often get the warning "Error: Service name is already in use on the network" at restart of homebridge in synology docker.  I enabled debugging in config-ux-i but no obvious clue as to where the problem comes from. I'm willing to dig further but maybe someone has come across this problem to focus my search.  I use multiple instances of mqttthing plugin and first thought it might be the fakelgato history logging but that doesn't seem to be the problem.

Strangely it always seems to happen at the same point of the restart. The Siemens dryer is my plugin and my code is:

this.client.on('connect', function(){
	self.client.subscribe(self.power_topic);
	self.client.subscribe(self.light_topic);
	self.log("I subscribed to " + self.power_topic + " and " + self.light_topic);
	});
this.client.on('message', function (topic, message) .....

power_topic is a plug, light_topic is an mqtt controlled light

Any hints where to look for the service names ?
Thanks
