apport information

** Tags added: apport-collected xenial

** Description changed:

  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?
