Title: Daily and Nightly cron jobs runs on every cron run » Daily cron job runs twice a day

After update to 7.x-2.0-beta8 cron runs not every time, but "only" twice a day :)

and so on.
My cron runs every 15 min.

Hehe :-). That's odd. I'll look into it.

I can't seem to get scheduled jobs to run according to the defined schedule either. For instance, one job is schedule as:

*/5+@ * * * *

& in the logs I have the last ten entires:

It's just like this for all my Ultimate Cron jobs. There seems to be no correlation between the schedule & when jobs actually run.

Using crontab scheduler with catch up of 86400, serial launcher, 3600 job lock timeout, 1 maximum number of threads, run in any thread, no poorman's cron, with my system cron running the Drupal cron script once per minute.

It seems there are actually quite a few reports spread out across a number of issues going back several years relating to this scheduling issue.

I'm closing this since Drupal 7 is now unsupported and there will be no more development on the Drupal 7 branch of Ultimate Cron either.

Thank you for taking the time and effort in reporting this issue, even though it never got resolved.
