Im unsure how these cron jobs work, not how to add them, but how they work inside.
If a cron job is running, and another one is startet (time or manually), will it start or not? i need to be able to have it wait finished a job before start another, and im unsure if its runs multiple of same job same time as im running some php scrapers, is the job locked until finished or something?.
Cancel job - why isnt there a cancel job button? lets say its a 30 min cron job, but log text says some fault, and i wish to cancel it, instead waiting it run 30 mins for nothing, is it possible to make such a chance quick in the source?.
Thanks in advance.
