I tested this for quite some time in a loop and also gave it a overnight run, but I couldn't hit this issue. I had kept low memory size guest, so that we could see more reclaim activity (which I also ensured by doing perf trace to see if we are going over that path or not while test was running). I am not sure whether this could be a timing issue or what. Maybe if you could share your defconfig, I could give a try with that on my setup once. -ritesh
