If a schedule is defined without schedule type it is running wild - the process is executed continuously.
I think this kind of schedule can be implemented better to run just one time on reboot.
Wouldn't be better to add a new type "OnRebootOnly" and use it when column if empty ?
And then make the column mandatory ?
I'm not sure it is clear that a unfilled type means "run once when server starts".
I agree with your assessment.
I committed an initial fix at 7f7bf09 - this is just to avoid the CPU running wild on this misconfiguration.
I'll keep this ticket open to implement the complete solution as suggested by .
Closing ticket - if required the suggestion from Nicolas, we can open a new ticket
