I have a pretty nice workstation, with 8 cores and 32G RAM.
A stupid little python program just killed it by consuming all the memory, driving it into swapping hell.
I couldn't even ssh into it - I started up ssh and went for coffee. On return I still didn't have a prompt. Had to power cycle it.
This is F23, everything is setup default regarding kernel memory policies, etc.
So, can we configure things to give a better experience? Can we make this default?
Maybe one for the devel list where they can do something about it. I haven't actually checked what the current Fedora policies are, since at work I use RHEL. I'd have thought the oom killer would get this. Really taking out all the memory with no swap available seems more likely to kill a system, possibly memory use can expand too fast, but on systems with some swap I've rarely seen things get to the point you can't get a virtual terminal up.
