OSMC randomly freezes

I’ve experiencing random freezing for some time now. Most often if video has been streaming for a long time, and I decide to stop it, it freezes. However, today it froze again when I tried to enter my external harddrive connected through an USB 3.0 hub.

It’s an RP2, not OCed, input power is 5V 2A. I’m not running anything on the USB-ports, everything external is powered by hub. I’ve set the disks to go into power saving mode (spin-down) after 5 or 10 min, don’t remember.

Any help will be highly appreciated.
