  • Sorry but no. That's not a greedy process problem. There is no greedy process. There's only kswapd behaving very badly with no apparent reason, as it was recognized in the discussion in the bugzilla entry I filed. Commented Mar 14, 2020 at 16:54
  • @JohnTerragon great then. I've read the thread, your case seems to be a too configuration-specific issue, which is going to be fixed. Though it's still possible that thrash-protect relieves the situation, due to it's problem-agnostic nature. If the kernel interrupts swapping the whole 15 GB when the swapped process is stopped, you may get a series of short freezes, Instead of a prolonged freeze: not ideal, but still better for the user experience, as this gives a chance to resolve it manually (f.e., manually kill the eater or something less important).
