Note that, if the task is already running when the task is triggered, the Job Conductor will wait for the current task to finish. If the task is not finished after 60 seconds, then the status of the task execution changes to 'misfired'. A misfired event also occurs if the trigger misses its firing time because of Talend Administration Center is shut down.
