Title:
  kswapd0 100% cpu usage

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  After the running the latest ubuntu for at least 2 weeks, I've noticed that kswapd0 started using 100% CPU on one of my cores.
  However, I have enough of RAM and not using swap (Swap: 11876344k total,    62336k used).

  The only thing I can do to remove the problem is reboot the system.
  I'm using Ubuntu 10.04.1 LTS server version without any kernel modifications.
