Random shutdown

I have Pinegrow installed on my chromebook (linux, GalliumOS) and performance overall is excellent, but Pinegrow is the only installed software that will at random times shutdown, without any warning, just vanishes from my screen!

It appears to happen when memory usage is running high. I save my work often (because of this) but if any of the developers get a chance, could you see if this is an issue with the linux version, as i can’t imagine there are many linux users who may report the same issue.

Thanks.
