Title:
  lowmemorykiller killing processes when swap still available

Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Saucy:
  Fix Released

Bug description:
  Hi there,

  I've upgraded a number of test systems to the latest Saucy beta. I've
  seen quite a few cases of processes being killed by lowmemorykiller
  with the following entries being logged:

  [ 291.565121] lowmemorykiller: send sigkill to 4476 (python), adj 0, size 8864
  [23515.006794] lowmemorykiller: send sigkill to 944 (update-apt-xapi), adj 0, size 44175

  The systems where this happens are kvm virtual machines with
  relatively modest amounts of RAM allocated (256 or 512 MB) with 2 GB
  swap. The swap is mostly unused when the kills occur.

  I searched around and could only find references to Android for
  lowmemorykiller and nothing on how to disable it. I tried the
  following without success:

  echo '9999,9999' > /sys/module/lowmemorykiller/parameters/adj

  Any ideas on how to disable lowmemorykiller or at least prevent
  processes to be killed rather than swapped?
