    I have 2 GB Memory on my VPS
    Websites that i have hosted are not using much memory. everything was fine but since 5 days ago my vps just crashes and i cannot access it with ssh or anything. it just returns timed out.
    before it happens memory is always on 90% or 80%
    the only way is to hard reset from client panel!
    once it comes up memory is around 30, 40 and everything is fine for some hours

    I am using nginxcp and I have CSF installed!

    Any one any idea why is it like this?
    these websites do not use high resources! i think something eats my memory to die!

    here is my top output

    Run the top command when the memory is 80-90%.
