I also have the same issue and would like a work around (for example some time out setting that can stop the scheduler if it has been executing more than X seconds) or a solution. Please.
Did you an answwer by another way? Did you find a solution ?
We always have the same problem.
We're also experiencing problems with the scheduler being hung in an "executing" state.
Did anyone get to the bottom of this? Is there a way to configure a timeout?
