> Key: SLING-4460
> URL: https://issues.apache.org/jira/browse/SLING-4460
> Project: Sling
> Issue Type: Bug
> Components: Commons
> Affects Versions: Commons Scheduler 2.4.4
> Environment: 3.3.4-11.omtr.el6.x86_64 GNU/Linux, java version
> "1.7.0_60"
> Reporter: Ken Russell
> Assignee: Carsten Ziegeler
> Fix For: Commons Scheduler 2.4.6
>
> Attachments: QuartzSchedulerComponent.pdf
>
>
> Sling jobs were not being processed on an instance due to the QuartzScheduler
> component being in a registered state (see attached image for the component’s
> state). The Sling job processor was not sending the job to our job consumer.
> From our error logs we could see that the job was created but the job
> consumer never received it. Looking at the crx we could see the job under
> /var/eventing. Our bundles & components were all active (we explicitly
> checked the component that consumes the job).
> Occasionally we see this problem on a restart of a production instance. This
> is an instance on our QA environment (we are hoping they are the same but
> will continue to monitor on subsequent production deployments).
> We noticed in the log file lots of exceptions related to QuartzScheduler
> indicating that the “Scheduler is not available anymore.” Truncated exception:
> {CODE}
