org.flowable.job.service.impl.asyncexecutor.ResetExpiredJobsRunnable

All Implemented Interfaces:

Runnable

Direct Known Subclasses:

TenantAwareResetExpiredJobsRunnable

public class ResetExpiredJobsRunnable
extends Object
implements Runnable

Runnable that checks the Job entities periodically for 'expired' jobs. When a job is executed, it is first locked (lock owner and lock time is set). A job is expired when this lock time is exceeded (this can for example happen when an executor goes down before completing a task) This runnable will find such jobs and reset them, so they can be picked up again.
