That's a known issue that was discussed already multiple times and it's already fixed on master.
Thank you. Now I found it in the forum. The only pre-compiled verions is the one in the preview right ?
Why could / should there be more pre-compiled versions then the ones in the preview section ? Thats what it is for, Its the latest version with commits included after the release of 5.11
But what i actually do is look up the solution that Anton commited https://github.com/traccar/traccar/commit/079eaa6ed49813f4050076ac45849f6e4334e45b
and then add it in traccar and recompile the server again. And that indeed solved the issue.
Preview is a build from the latest master.
After i upgraded from 5.10 to 5.11 I am noticing the alarms are duplicating.
I am only testing with 3 devices, each linked to a single user. some type of alarms are duplicating 4 times, other are 5, 6 or 7 times.
Ex: one phone, connected to just admin, has 1 event-low battery and 7 alarms. and always 7 alarms each time I test
