Since I upgraded from OpenHAB 3.4 to OpenHAB 4.0, I noticed that sometimes OpenHAB stops visualizing data in a chart. It happens today (see the following screenshot taken at 8h20)
The current version of OpenHAB is 4.0.3. It is hosted within a Docker container on my NAS (Synology). I have to stop and restart the container to fix the problem. It seems that it is an issue with the persistence service (RR4D4J) since data were not recorded. When I restart the OpenHAB container, data are again stored but there are missing data (see the following screenshot)
I had a look into the log file and did not see a warning/error when OpenHAB stopped storing tha data (around 4h42 this morning).
Any advice to fix the problem ? Thanks in advance.
