I noticed that my mosquitto broker looses connection every day at 06:25… every day.
Went back in the logs, but I only keep the last four days, so I do not know when this started.
I have owntracks in stalled, and ot-recorder n the same rPi… but do not see, whether this at all related.

Any ideas on how to get to the bottom of this?
I am not too worried, but can imagine, since I heavily rely on MQTT messages, that I may miss some messages, while mosquitto reconnects – which seems to take only 12ms…
Should I be worried at all? May not in practice, but wanting to run clean and well behaving systems, I do wonder.
