MaxListenersExceededWarning after network reboots

[Eikkargh]

I am running a modifier version with statusKeys modified for a dehumidifier. It is running as a service on the same machine as the MQTT Broker. I currently have a forced reboot on my router once a week. When this happens the node gets stuck and give the following errors:

Apr 22 04:01:09 raspberrypi node[20234]: (node:20234) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 message listeners added to [Socket]. Use emitter.setMaxListeners() to increase limit
Apr 22 04:01:09 raspberrypi node[20234]: (Use `node --trace-warnings ...` to show where the warning was created)

I have not been able to catch any warnings with --trace-warnings but will keep an eye out.
For now I have upped the maxListeners to 15.
