Azure Scheduled Web job is triggering twice sometimes

We have an Azure WebJob which is scheduled to run at 8:00 AM UTC daily(CRON - 0 00 08 * * *).Most of the days it is triggering correctly but on some days it is triggering twice (Second run is occurring ~10 secs after first run ). I can see in the web job history that when it triggered twice,first run's trigger property(from WebJob History JSON) is showing as "External - " and second run trigger property is showing as "Schedule - 0 0 8 * * *" but we don't have any external services triggering this WebJob.

When i checked the Job scheduler log for more details, "Web Job Invoked" status is only present for those days when the webjob got triggered twice.

Your problem appears to be that you appear to have two different things triggering your WebJob:

  1. You probably have a settings.job (wiki) with a cron expression.
  2. You may also have an Azure Scheduler Job Collection hitting your WebJob from the outside (possibly with a different schedule, which is why they don't always match).

Suggestion is to get rid of #2, and only keep the internal WebJobs scheduling via settings.job.
