Synology DS415+ NO hibernation after 1.6 update

Hello,

I have Synology DS415+ and before version 1.6 it was hibernating after 20 minutes and sometimes waking up. After I had updated Serviio to 1.6, NAS stopped to hibernate.
I checked logs and nothing except Serviio updated happened on that day.
Please help, I don't want hard drives to spin 24/7.

Thanks
