> The scheduler gets stuck without a trace or error. When this happens, the=
 CPU usage of scheduler service is at 100%. No jobs get submitted and every=
thing comes to a halt. Looks it goes into some kind of infinite loop.=20
> The only way I could make it run again is by manually restarting the sche=
duler service. But again, after running some tasks it gets stuck. I've trie=
d with both Celery and Local executors but same issue occurs. I am using th=
e -n 3 parameter while starting scheduler.=20
> Scheduler configs,
> job_heartbeat_sec =3D 5
> scheduler_heartbeat_sec =3D 5
> executor =3D LocalExecutor
> parallelism =3D 32
> Please help. I would be happy to provide any other information needed
