[Support] Error: addMembership ENOBUFS
This may not be a Shelly problem but since it’s only this plugin generating the error I’ll start here. Thanks in advance for any guidance.

**Describe your problem**
The Shelly Homebridge plugin constantly crashes with the error in the description. Also see attached screenshot. 

It was running fine for ages. I updated QNAP container station (docker), home bridge from 1.6 to 1.7. This necessitated changing the containers networking config (the IP address changed) and I also deleted Homebridge accessory and persist folder contents. 

All my plugins still run but Shelly fails. 

I get no google hits for Homebridge and ENOBUFS

**Describe what you have tried so far**
I have tried clearing the Shelly accessories (2 lights) in the Homebridge settings and I have deleted and re-installed the Shelly plugin.
I tried disabling other some plugins in case it was resource. 
I changed the admin port and then disabled it in case it was a port conflict with the host. 

**Environment:**
 - Shelly device(s): 1 X Shelly 2.5, 2 lights
 - Plugin version: 0.20.0
 - Device running homebridge: QNAP NAS under container station and portainer.
