[Astro] Sometimes the event doesn’t get scheduled for all of the Astro Things

[bib2]

I have 3 astro things defined.
1x sun
1x moon
1x sun-additional (workaround with another location for getting a small offset)

Most of the time, i get 30sec after midnigt 3 schedulings for the things. But sometimes, i only get 2 schedulings. This happens sometimes 2 times a week, sometimes it is working a month without any problems. After i restart openhab service, i check the logs and then i get 3 schedulings again.

Now i´m on openhab 2.4 snapshot #1338, but this error is there for long time, maybe 1 or 2 years, every now and then.

I have a workaround, which is comparing now with the time of the astro-sun event sunrise start, but in cases the new day is not scheduling, it compares with the datetime of the day before. (the datetime is persisted in my installation, so i always have a datetime in my item).

Here is more information about the problem...

@triller-telekom maybe you can have a look into this.

I have debugged the scheduler code in the past and already moved the time to 30 seconds after midnight because it was more reliable this way. Though, this was just a guess of me.

I have absolutely no clue what's wrong with the scheduler in this case. We will probably have to live with it until someone works on replacing the scheduler with #4295.

I have the same issue. For me it seems that only happens after a restart and it normalizes after a few hours after restart, but needs more testing.
I'm on 2.4 M6 now and I didn't have this problem before.

can you guys try M7?
One user reported that he doesn't have this issue anymore on M7

I was the one who wrote this... I need some further testing, but I haven't had this error since then...
