Tickets don't get created, but there should be a trace in the database. Take a look in the db.scheduler_run.traceback field of the task in question.
The scheduler_run.status should be FAILED and you'll see the run times, etc. in other columns... Basically, everything about the scheduler is in the database, in db.scheduler_task, db.scheduler_run and db.scheduler_worker. All it needs is a bit of front-end programming, and you can get all the statuses, etc.
