----------------------------------

             Summary: rescheduled failed jobs increments queued jobs counter
                 Key: SLING-5315
                 URL: https://issues.apache.org/jira/browse/SLING-5315
             Project: Sling
          Issue Type: Bug
          Components: Extensions
    Affects Versions: Event 3.7.6
         Environment: seen in sling.event 3.7.6
            Reporter: Stefan Egli
            Assignee: Carsten Ziegeler
             Fix For: Event 4.0.0


When a job fails and is rescheduled (eg in 60sec), then the statistics are skewed:
* a job start calls {{stats.addActive}} which decrements {{queuedJobs}}
* for a failed job, {{queue.finishJob}} indirectly calls {{stats.failedJob}} which increments {{queuedJobs}} again
* then the job is marked for rescheduling in eg 60sec
* then upon rescheduling in {{queue.requeue}}, indirectly {{stats.incQueued}} is called, which increments {{queuedJobs}} as well

With the result that the {{queuedJobs}} counter is incremented each time a job fails - even though there are not really more jobs in the queue.
