Title:
  Ubuntu gets slow and freezes, because 'invisible' processes use all
  memory

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I usually suspend my computer (HP EliteBook 8560w) to RAM if I
  tranport it or I don't need it and I restart it only once a month or
  so. However, since a few weeks, my computer gets slow, sluggish, and
  ultimately freezes after using it for some hours, because some
  'invisible' processes use all the RAM (8 GB). When I notice in time
  that there is no or little memory left in RAM so that the computer
  starts to use swap memory and I immediately close all programs, I can
  restart the computer before it gets unresponsive. I have to restart my
  computer at least once per day (often by pressing the on/off button
  for a long time, when I did not manage to restart the computer before
  it became unresponsive). Although a lot of memory is used, the
  processes that use most of the memory are not listed by "System
  Activity" or "top" (I will attached a screen shot and a text file that
  illustrate this). Hence, it seems that some 'invisible' processes use
  nearly all of the memory.

  I ran MemTest86 (from the boot menu) but it did not find any errors.

  I did not use 'apport' to report this bug, because it does not really
  work:

  https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1539263

  but I managed to save the information collected by apport, which I
  will attach.

  Which further information do you need?
