Multiple CronJobBase running when ALLOW_PARALLEL_RUNS is set to False about django-cron HOT 3 CLOSED

Thank you for your answer. I had set default Django cache, which is django.core.cache.backends.locmem.LocMemCache. I changed it to django.core.cache.backends.filebased.FileBasedCache and it started working. It is because LocMemCache is per-process (according to documentation). Each process has its own private cache instance, which means no cross-process caching is possible. That's the reason why the cronjobs couldn't see each other locks and they run every time. It would be helpful to mention that in README or documentation. Thank you for your help.

Make sure you have a caching layer set up and configured, as that's where the app maintains state of which jobs are currently in-progress. Without that, the feature will silently fail and re-trigger the job every time the crontab comes up.

@eriktelepovsky works like a charm.
