description |
My laptop has 4GB of RAM and ~6GB of swap configured. After my most recent kernel upgrade in raring, I am noticing the system has started swapping itself to death; the desktop becomes completely unresponsive, and in some cases it becomes unresponsive even over SSH.
Looking remotely with SSH, I find that kswapd0 is using up nearly one full core. I have no idea *why* - I have vm.swappiness set to 30, and 'free' shows that over 1GB of RAM is still being used for buffers, so there really shouldn't be any memory pressure. Despite the fact that there's only ~400MB of swap used, which should certainly fit back into system memory, 'swapoff -a' fails with a 'Could not allocate memory' error. If I set vm.swappiness to 0, the swap usage decreases, but *very* slowly: after over a half hour, there's still over 400MB of swap used. And I don't have any idea what kswapd is doing at this point, but it's still very busy; and even after setting vm.swappiness=0, the system has managed a second time to get itself into an unresponsive state, with swap looking like the culprit.
dmesg shows nothing (which I will try to demonstrate by attaching logs from the machine in question, once it's responsive enough to let me run apport-collect). |
