On Home Assistant startup, there is always an error like this pops up:

2026-01-07 22:23:49.254 ERROR (MainThread) [homeassistant.components.websocket_api.http.connection] [140711007067392] Node-Red from 172.16.10.1: Client unable to keep up with pending messages. Reached 4096 pending messages. The system's load is too high or an integration is misbehaving; Last message was: b'{"type":"event","event":{"a":{"device_tracker.unifi_default_ce_7f_02_83_2d_9e":{"s":"not_home","a":{"source_type":"router","mac":"ce:7f:02:83:2d:9e","host_name":"","oui":"","friendly_name":""},"c":"01KED8Y7G6V52A81RD7TEH41AH","lc":1767824629.2545705}}},"id":7}'

What can I do to get rid of it?
