Open Source Document Management System | OpenKM

Hello to all
I installed on a VM OpenKM 6.3.1 Ubuntu 16.04 server.
For a few weeks autoscripts operated smoothly. For some time it is not automatically launched, and you must do it manually. I can not fix the problem.
Have you any suggestions?
Thank you!

We are talking about crontab scripts or automation events ?
Review them, if you are executing crontab task, ensure you are using system token into, not executing methods with parameter token set to null value.
