[BUG] High CPU usage without any active connector

[nightcore500]

I am observing an issue with a freshly set up ThingsBoard Gateway (3.7.0) running in an LXC container with Debian 12.9 & Python 3.11.2.
The gateway is currently only connected to ThingsBoard. No connectors are active at the moment.
Nevertheless, the Python process is causing 100% CPU load:
