   hi, I am still running into this behavior.  Using the provided Airflow 2.3.4 image with Helm chart 1.7 and the scheduler restarts every 5 min. I logged into the scheduler pod and ran the liveness probe as listed in teh config 
   ```airflow@bairflow-scheduler-0:/opt/airflow$ sh -c               "CONNECTION_CHECK_MAX_COUNT=0 AIRFLOW__LOGGING__LOGGING_LEVEL=ERROR exec /entrypoint \
                 airflow jobs check --job-type SchedulerJob --hostname $(hostname)"
   No alive jobs found.
   airflow@bairflow-scheduler-0:/opt/airflow$ echo $?
   1```
   and it always returns exit code 1.   based on https://airflow.apache.org/docs/apache-airflow/stable/logging-monitoring/check-health.html#scheduler-health-check-server
   we switched the livenessprobe command to ```scheduler:
     livenessProbe:
       command: ["bash", "-c", "airflow jobs check --job-type SchedulerJob --allow-multiple --limit 100"]
   ``` and it returns 0 and appears the solve the issue.
