No new log (INFO/WARNING/ERROR) into “/var/log/openhab2/openhab.log” .

A reboot fixed it.

What could it be?

Hi Sim,

have a look here

Hello Christoph,
I thought they were two different problems, but on restart the RRDs lost the new values.

Sim

I’m afraid I can’t follow you. Can you please explain your thoughts in detail to me. Thanks.

Which new values were lost? On my setup, which was affected, rrd4j did not store any values between the DST change time umand the restart of OH.
I understand that as part of the problem and that such has been solved in OH2.3 actual snapshot.
