@jihoonson
I dont have the logs anymore but the error occurs regularly now. (I will post the logs as soon as it appears again)
Maybe its not related, but we figured out that our postgres have a very large number of non active tasks in the postgres database.
It seems that the old tasks are not getting cleaned from the database anymore (I think this was the case in our Druid version < 16.1)
The result of this is that the Druid UI was not responding anymore for the "Task"-Tab. Or every time the UI fetches something from the database. And the overlord quit with an Heap Space Error every time the "Task"-Tab was opened:
I even granted the overlord 5GB of Heap (before it was 1GB) but it was not helping. The only thing that helped was to delete all of the non active tasks in the database.
