Stuck Delayed Jobs

Some or majority of the scheduled delayed gets stuck, and sometimes the only thing that activates the stuck job is to schedule another to kick off the process.

Any insight on this anomaly.

Thank You.

No file, test, or entry point is named. Start by reproducing a scheduled delayed job that remains stuck until another job is scheduled, then trace the delayed-job and worker processing paths. Done means the cause is identified and delayed jobs activate without requiring a subsequent job to be scheduled.
