Please check if some error is logged.
If an error or an exception happens on cron process, it is stopped.
We arr working on evolution for next version to detect this and restart it automatically.

If there is no error, possibly it is because of your PHP configuration.
Cron is a process that runs forever, but for this, your PHP configuration must allow set max_execution_time to zero.
There are soem configurations that forbid this.

Another possible source is that your PHP is stopped for maintenance (some operating teams stop PHP before backup of DB).
If so, Cron will try and restart automatically, but it is possible only when a new user corrects (we need to detect some interactions to check cron running)

No error on log file.
I change value for max_execution_time =30 to 0
I restart Apache server, and I will see if Cron re-stop ...

I'd changed max_execution_time=0 but I have always Cron stopped...
I must everyday to start it on the morning...

Hi,

It seems your PHP is stopped during the night.
We have a system that should restart it automatiucally at first login of any user, but it does not seem to work.
