### Deploy method
Docker
### Z-Wave JS UI version
9.0.3.c37f5a4
### ZwaveJS version
12.0.2
### Describe the bug
I am running a docker instance on my QNAP NAS.
I have several containers utilizing almost 0% CPU utilization.
When I start the zwavejs container I have continuous spikes to my CPU from 10-60% which can be seen on my dockerd process.
The actual container is 0%.
The dockerd starts like this
container-station/dockerd -H tcp://0.0.0.0:2376 -H unix:///var/run/docker.sock --bridge=lxcbr0 --tlsverify --tlscacert=/etc/docker/tls/ca.pem --tlscert=/etc/docker/tls/server.pem --tlskey=/etc/docker/tls/server-key.pem --storage-driver=overlay2 --dns 10.0.3.1 --data-root=/var/lib/docker --exec-root=/var/run/docker --pidfile=/var/run/docker.pid -D --userland-proxy=false --config-file /share/CACHEDEV2_DATA/.qpkg/container-station/etc/docker.json
and the zvavejs docker-compose.yaml file is the following
```
version: '3.7'
services:
zwavejs2mqtt:
