Jolla released their first smartphone in 2013 after crowdfunding but ultimately the Sailfish OS focus the past number of years now has been offering their software stack for use on other smartphone devices.

This sentence took me so long to decipher. For others struggling, read “has been offering” as “has been to offer”. It’s saying they tried hardware, but ultimately they’ve been offering their software stack to other hardware instead of making their own.

I’ve had this issue and for me using earlyoom helped. My computer ram would fill up and the kernel oom killer wouldn’t trip in time to be helpful. It could just be your memory filling up and your computer not killing the offending process in time.
