It doesn’t happen often, and I have a multi user system with unpredictable workloads. It’s also not about swap filling up, but giving the pretense the system is operable in a memory exhausted state which means oom killer doesn’t run, but the system is unresponsive and never recovers. Without swap oom killer runs and things become responsive.
