Since I've upgraded from ubuntu 13.04 to 14.04 (and before 13.10) my system get's to it's knees when the memory get's full and has to start swaping..

Of course I know that a performance penalty should occur, but this is too much.. even the pointer stops working for a few seconds and one time I had to manualy reboot the notebook (I wasn't unable to switch to a console with ALT+Fx to kill some process). This usually happens with Google Chrome when I go to far opening tabs and I have a few other apps running, still I expect from linux to behave much better than this and I think this started happening since 13.10 an 14.04.

I'm using "System Load Indicator" (by Hofmann) and when the memory get's full the cpu load get's to 100% and if I don't start inmediately to close stuff, caos is inevitable.

Here is my notebook hardware specification:

Any directions how to diagnose or solve this issue? Thanx!

----- EDIT1 ------

Ok, I will expand according to request, I set up a simple batch file to log system usage every 2 secs:

#!/bin/bash

STAMP=$(date +"%H_%M_%S")

echo -e "** memory usage **\n" >> $STAMP

free -mh >> $STAMP

echo -e "\n** top 20 process by memory usage **\n" >> $STAMP

ps aux --sort -rss | cut -c-120  | head -n 20 >> $STAMP

echo -e "\n** top 10 process by cpu usage **\n" >> $STAMP

ps aux --sort -c | cut -c-110  | head -n 10 >> $STAMP

echo $STAMP

Then I've run it with watch every 2 secs and started toying around..

This is a snapshot of my system at moment zero, I have a bunch of apps open but everything is smooth:

Why is chrome using all that CPU when the memory starts to get full? Even if chrome is the "culprit", isn't the OS responsability to stay operable under heavy load?

  • You will need to provide details on memory utilization ( `free -m for a start ) and what process is using all of this cpu time. – psusi Jun 13 '14 at 1:36
  • I've updated the post @psusi, anything more that is useful? – pragmatic_programmer Jun 13 '14 at 22:58
  • Do you have the same problems when opening the same web pages using different web browsers instead of chrome? Are the particular web pages resource hungry? (See chrome://memory to see memory usage per tab) – Mark Jun 18 '14 at 3:31
  • No, I open a bunch of different pages.. still, does this matter @Mark? I mean if an app is behaving badly the OS should remain operative.. – pragmatic_programmer Jun 18 '14 at 14:46
  • Chrome process using up an entire core is often because a particular webpage is too demanding. OS will become less responsive if approaching resource limits. Try vmstat for more info, see jumpcloud.com/my-linux-server-is-very-slow – Mark Jun 23 '14 at 0:46

Add more memory, if possible.

General information about low memory: Preventing low memory problems (windows specific, but the concepts are similar)

The Linux kernel provides a tweakable setting that controls how often the swap file is used, called 'Swappiness'
