Order gets stuck in job chain from time to time

Starting Situation

How to disable microscheduling for releases before 1.7.3

You can disable the microscheduling in your JobScheduler environment manually by setting the following parameter in ./config/scheduler.xml:

<config>
...
	<params>
    	<param name="scheduler.old_microscheduling.enable_for_jobs" value="false"/>
	</params>
...
</config>

A restart of JobScheduler is required to apply this setting.
