I have a scheduled report using a public schedule on Pentaho Community Edition 4.8

The set up is very basic: one report with fixed parameters sent to the same recipients every workday.

Every time I set it up, the report runs as scheduled and gets sent. Then, it stops being sent. I have to re-schedule (and sometimes even that doesn't work).

There's nothing on catalina.out or pentaho.log about it.

Has anyone had this problem?

Where else can I look for quartz logs?

Is there a way to "force" the execution of the schedule with cron?
