Comment 33 for bug 721896

I'm seeing this on Precise with a computer that has weeks of uptime between reboots. 50% wa in top (one of two cores), 100% kswapd0 in iotop (no read of write throughput reported). This keeps happening with some 200-300 of MB free memory as reported by free -m (but significant swap use, so total used > physical memory).

Turning swaps off and on again usually helps. I can't try running without swap because there isn't enough memory to actually do much with the computer.
