AEM Scheduler running even if scheduler is disabled and Bundle is stopped

Hi,

I had created a custom scheduler for sending emails based on inbox tasks in aem. It was working properly until a day ago when suddenly, even if the scheduler is disabled, and the bundle is stopped, it is still somehow running and I get emails for newly created tasks. But in the project logs it shows that the scheduler has been stopped and no evidence of the code being executed. So a different scheduler is somehow still running and it is not part of this bundle?

Please let me know how I should go about fixing this issue and finding/stopping that scheduler.

Thanks.

Hi @abinav_98

Scheduler or we can say thread can still run even if the bundle is down. We have to remove scheduler on deactivation of scheduler service. You can remove it in @Deactivate annotated method of your service. Find the sample snippet:

@Component(immediate = true)
public class TestScheduler implements Runnable {

    @Reference
    private Scheduler scheduler;

    private String schedulerId = "Scheduler";
    
    @Activate
    @Modified
    protected void activate() {
        addScheduler();
    }

    @Deactivate
    protected void deactivate() {
        removeScheduler();
    }

    private void removeScheduler() {
        scheduler.unschedule(String.valueOf(schedulerId));
    }

    private void addScheduler() {
        ScheduleOptions scheduleOptions = scheduler
                .EXPR("");
        scheduleOptions.name(String.valueOf(schedulerId));
        scheduler.schedule(this, scheduleOptions);
    }

    @Override
    public void run() {
    	//what needs to be done
    }

}

Hope it helps!

Hi @nupur_jain , thank you for the response.

Yes, I am already using the code snippet you shared in my code.

@Deactivate
protected void deactivate(AkamDASHSchedulerConfiguration dashOSGIConfiguration) {
log.info("DeActivate method");

removeScheduler(dashOSGIConfiguration);
}
private void removeScheduler(AkamDASHSchedulerConfiguration dashOSGIConfiguration) {
log.info("RemoveScheduler method");

// unscheduling/removing the scheduler
scheduler.unschedule(conDASHSCHEDULERCONFIG);
}

It was working properly until a day ago. It should show the scheduler going to run method in the project log if that's the case but it doesn't. So it looks like there is a duplicate/cached scheduler which is somehow still running.. Any idea how I should solve this issue?

Can you check if there is any active jobs running ? If you check /var/eventing/jobs , may be you can find any active jobs running.

Good point, I can check that. However the URL your provided doesn't seem to work (/var/eventing/jobs). Did it get moved?

You can check existing jobs under:/var/evening/jobs and also check the scheduler config under: /system/console/configMgr just to make sure the scheduler is disabled or removed.
