If you don’t have swap then create some, that should help prevent you running out of RAM.

the only way out I know (if you know safer ones let me know!) is to turn on off manually the machine

Enable the magic sys req key, and use REISUB.

[HowTo] reboot / turn off your frozen computer: REISUB/REISUO

Difficulty: ★★☆☆☆ This tutorial was created because people are using a hard power off during freezes, so this will teach you how to turn off your computer when everything is frozen using softer means. So whenever you see someone saying they had to “Power Off” or “Hard Reset” their system without doing a REISUB, please send them here!
