I have a strange experience with current beta (withour background_process ):
* All cron jobs seem to run smoothly
* But "Ultimate Cron Launcher Serial cleanup" logs on every run "Cleaned up 21 expired locks"
Also noted
* I don't understand the difference between the green checkbox and the blue info status
* When i kept running "drush core-cron" all jobs were run every time, until i changed that to "drush cron-run". Maybe a message is useful like "Last cron was run from core. To benefit from ultimatecron run drush cron-run instead of drush core-cron"
Maybe the "expired locks" are just a leftover from the wrong drush command. Then we have it here in the knowledgebase.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
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.
