The check that I mentioned above is actually the deletion which you mention: run-crons looks for the state file for the given interval and - if it is old enough - deletes it. The part that executes the individual cron scripts is only executed if there is no state file. The first thing it then does is to create a new state file. In pseudo code: 1. look for period state file that is older than interval + 5 mins found one? delete it 2. Look for period state file none found? create state file execute cron scripts for that interval -- Grüße | Greetings | Qapla’ Please do not share anything from, with or about me on any social network.
