> @dwiajik @stablum - is there any chance you have some customisations (plugins ? ) or users running DB operations (backfill? API calls? UI modifications) that might have caused the deadlock? Looking at the code, my intuition tells me that this must have been something external. Having the server logs could help to pin-point it. I once experienced this while running a dag with many tasks. Parallelism was 64 and I have 4 dags. No concurrency limit on the dags, the tasks finishes in 20s and at one point the scheduler crashed. I will try and see if I can get it again -- This is an automated message from the Apache Git Service.
