[Bug 1540013] Re: Ubuntu gets slow and freezes, because 'invisible' processes use all memory
I updated the BIOS to the latest version (F.60) a week ago.
Unfortunately, I did not notice any improvements and the problem still
persists :-(
$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
68SVD Ver. F.60

Title:
Ubuntu gets slow and freezes, because 'invisible' processes use all
memory
Status in linux package in Ubuntu:
Confirmed
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?
