OMV crashes(?) every day at the same time [Banana Pi Pro]

Hi, for the last 3 days around 17:17 I have lost connectivity with my network drives and all network connectivity to my Banana Pi Pro pushing the hardware reset button fixes it. Going by syslog, it seems the machine restarts but for some reason loses connection to hard drives. Does anyone have any idea what might be causing it? I've attached syslog output from 1 hour before the 'event' until a couple minutes after the 'event'. Thanks.
