Cronjob RUN_EVERY_MINS=1 not actually running every minute

[jeremych1000]

Not sure why the cronjob isn't being run every minute :/ sometimes it does, sometimes it doesn't.

I saw #91 (comment) but is there any solution to this?

Any other information I can provide?

I'm experiencing the same issue.

Maybe it is caused by previous other CronJobBase classes still running.
The actual command is not calling the different CronJobBase classes in parallel.
They are executed iteratively.
See PR #88
Maybe that helps

Use manage.py cronloop -s where s is sleep interval in seconds. 300s by default
