I'm just testing multiple Schedulers in 2.8 b1235 on our dev machine and have got everything working but I've noticed that the 'Pause Scheduler' tick box does not appear to actually pause the Scheduler nor does the 'Stop' button actually stop the Scheduler?
Am I missing something or are you guys aware of this?
We will have to do a screen sharing session to look at this further.
I've ran some tests here using your config files and scripts and cannot reproduce the problem. Jobs queue up when paused and are executed when unpaused with both schedulers. Jobs are stopped when stopped and start when started, again for both schedulers.
