Hass.io hangs after short time running

Hi there.
I’m running HASSio on a Raspberry pi2 and have a Aeotech Z-wave usb connected.
And for some reason the HA stops working after a day or couple of days.

I also have terminal Add-on installed, and sometimes i can connect to the terminal and run “hassio ha restart” and then HA works again. And sometimes even the terminal is unreachable.

I’ve checked the “hassio ha logs” but couldn’t really find anything i thought was related.
I’m quite new to HA and HASSio and i don’t really know where to start looking.
Can anyone please help me?

HASSio version 0.60.1.
