I recently installed this system and sometimes when it should hibernate it ether come back to lock screen or get stuck with black screen and making laptop really hot (usually second variant happened overnight). I managed to recreate this issue with firefox opened, it doesn’t matter how many tabs are open. Journal says it Cannot allocate memory. I have 7 gigs of ram and 25 of swap. Could somebody please help me with this issue i dont really know what logs might be needed so i attach terminal outputs of status systemd-hibernate, please tell me if any other logs would be useful.
Failed hibernation, with firefox window opened in which there are singular new tab:
