High CPU usage? (Device announce spam)

[AnderssonPeter]

Hi I installed zigbee2mqtt on a raspberry pi 3, yesterday and added some devices.

Everything was fine and dandy, but between ~00:00 and ~04:00 it stared to use 100% CPU, then again around 09:00 it started again where I shutdown the container as I was at work.

But when looking at the logs I can see that one of my devices announces it self over and over again, causing a huge amount of logs and mitt traffic.

The following is logged over and over again (multiple times per second)

2023-10-19 08:53:51.052	
Zigbee2MQTT:debug 2023-10-19 08:53:51: Device 'outside_entrance' announced itself

2023-10-19 08:53:51.142	
Zigbee2MQTT:info  2023-10-19 08:53:51: MQTT publish: topic 'zigbee2mqtt/bridge/event', payload '{"data":{"friendly_name":"outside_entrance","ieee_address":"0x000b57fffe260903"},"type":"device_announce"}'

What could be the cause for this? (It's only one device that does this)
Is the device broken? Are there any thing I could try to fix this?

The device is a Ikea light that's a few years old.
