Unable to serialize to JSON

I have recently (after upgrade to 0.108) had a problem that the logfile grows extremely quickly. The following message is written to logfile at short intervals (approx. 20 MB per hour).

Does anyone have a similar problem? Any experience, what causes this behaviour?

You are not alone. Someone else has reported this issue in the Home Assistant Core repo:

I have it too

I have this issue too - but there seems to be no movement on it anywhere…
