First, please excuse my english. It's been some years since I "used" it.
I'm a complete noob if things tangents linux.
Let my describe the problem situation:
I use a redmine appliance (V11) within our company. In this appliance I integrated an so called "whining" addon which should send an email, if tickets are pending for quite some time.
In the prior redmine appliance (V10) this worked without problems. Now it seems like cron never starts the job - no matter what periods of time I set. I also changed the user from www-data to root - but this also didn't brought a solution.
