Scheduling not working - Smart and Full

Hello everyone,

I'm very newbie in ZExtras, i'm using 1.8.16 version, Zimbra 8.0.4 - RedHat 64bits.

Everytime I click in "Run SmartScan" or "Run FullScan" it works correctly,

But schedule does not work.

================================
How it is:

- Enable Scan Operation Scheduling is ENABLE
- RealTime Scanner is DISABLE
- Daily SmartScan at: 11:00 am
- Fullscan on: Wedn
- Run SmartScan at Startup: Disable
- Data Retention Policies: 30 days
================================

In ZExtras Notifications, there is no schedule jobs, just the one that I run manually.

There is a log, or some "cronjob" that I can look at the 'Schedule time' to see what is wrong?

Can anyone help my team with this?

Thanks
Ícaro Ribeiro.
